View Full Version : Wow..seriously... more problems

There is more problems, again. I'll let the video's do the talking.

The list of new parts is:

Fuel filters
O2 Sensors
Intake manifold gaskets
Belts
Tensioners, pulleys
Valve cover gaskets
Cleaned injectors
New injector O rings
Spark plugs
Intake boxes and filters
Cleaned DK motors
Starter
Cabin filters
Caps
Rotors
All new rubber hoses up to the DK's
New batteries

Literally all of these items are less then 2,000km ago.. I've never had a car have this many problems, am I missing something here? :mad

My guess is this is something to do with ignition, because the car can keep cranking and just nothing happens no catch. Getting sick of guessing with this thing though, just want to drive it/start fixing the body.

Here are the videos:

Are they the ones on the vacuum lines towards the DKs? Are those the things you are talking about? Also there is smell of unburnt gas in the exhaust.

Jenya my hat is off to you.... you have the patience of Job. With all due respect your saga could be a text book example for new owners of a car that is behind the maintenance curve they are looking to buy. You sure as Hell have earned the right to enjoy that car for awhile.

how about the crank positioning sensor?
i don't know, if i would rev her like that.
the way she runs

Crank positioning sensor? Is there any certain way of trouble shooting this particular problem. This only seems to be a problem when the car sits over night in the cold. Doesn't seem to do this when you crank the car in the garage, or after it got through this problem after the night.

Like I just went into the garage, and boom car cranked like nothing, running super smooth and everything.

Crank Position Sensors (plural) there are two of them. They need to have the correct gap between them and the notched wheel on the vibration damper.
Also, you might want to look at the ignition coils.....

Yes its really odd.. only cranks like that when it sits outside in -20C weather overnight. (Even plugged in with oil heater and 5W30)

Keep in mind that you're trying to run two engines at once, sorta. Make sure the controls and sensors are connected to the correct side of the motor. O2 sensors, crank position, purge valves, fuel pressure, etc. It's easy to get them crossed, especially after intake gaskets. Remember that the manifolds run the other side of the motor.

but the car runs fine inside the garage.

Correction - the car starts and drives like a dream when it hasn't sat outside all night long in the -20C weather. Seems like the car only does this if you let it sit for about a day. If you start it every 5 hours, even in the -20C weather outside, seems to start fine. Just when it sits for a extended period of time...

Oh the gremlins of the 8 haha... never seize to suprise me. :eyecrazy

Have you gone thru the entire tank of gas yet?
You could try something to soak up water in the tank if there is any ... couldnt hurt possible badd fuel.
Something is freezing on the car , would be my guess.
Worse come to worse you might end up haveing to track down the problem while the car is acting this way not when its warmed up.

If it was the Crank senors it shouldnt start I have a E34 520i and every once in a while it would start misfiring and wouldnt rev over 1500rpm sounded as if it was firing in the wrong order and the stink that came from it you could drive for months and then bingo this happened didnt matter what type of weather some times I had to let it sit a while then start again and it would drive prefect
The reason I say it not the crank senors is because when searching for the answer for mine I found Crank senor fault no start camsenor will cause misfire hope this helps
when E34 misfired it really sounded as if it was firing in the wrong order rather than being off a clyinder
cant tell from the sound of yours

First of all if you keep that starter engaged for that long of a time you WILL burn it up.
Have you checked the plugs? Try starting again and then pull a plug on each side of the engine. Is either of them wet? If not, then you might be looking at Fuel Pressure regulators. If they are wet, you aren't getting spark (might look at ignition coils). The problem with ignition coils is that when you meter them with the ignition OFF, they can show the correct resistance. It is under load that you have the problem. I don't recommend trying to measure them while the engine is running - alot of juice running through them.
I had a similar problem where the car would actually be running, then start "misfiring" and then having a hard start, waited a few moments and everything ran great again. It turned out that the wires on the CPS were craked directly underneath the clamp that holds them to the timing cover. There was no way to visually see that there was anyting wrong - they even metered out okay. I replaced both and car runs great.
Do you have access to 2 known good ignition coils with which to troubleshoot? (any 8ers close by?) It would be worth it to either rule them out or to say they are the culprit.

Unfortunatly, I do not have any 8er's near by that I know of. Seems like there are none in Edmonton...

I will try the above procedures you told me to test with my spark plugs.

Merry Christmas!

Just went and did what you advised. Plugs on the right side of the engine are basically soaked. The ones on the left were not as bad, but still damp.

Also the plugs have black residue over them, which under my impression is improper mixture (no fuel or spark) am I correct? The plugs are brand new so it is for sure not their problem.

its a nice looking car though, i wouldn't leave my car in -20 degree weather even if it did work when i turned it on. just do ur best to keep it in garage, if it rlly annoys u just take it to repair man to get it checked out.

imo, these cars will allways be challenged in extreme cold weather and what yours did is exactly how i would expect the 12 to start if left outside in sub zero conditions.these cars have nothing to assist cold starts"nothing"!.dme's will attempt to enrich mixture and slightly raise idle using the eml but this the only assist the engine gets.with all the parts you have tossed at the car i would opt for two new coils,$68 each and could have a dramatic effect on cold weather starts.imo cps sensors either work or they dont,as long as they are gapped correctly and the sensors/crank pulley are reasonably clean the system should work.hang in there,exotic rides are finicky but worth it

Jenya
12-25-2008, 11:43 PM
Everyone thank you for the offers for testing. I think I will just buy some more parts(coils), it doesn't annoy me too much spending money on this thing - it would just be nice if I could drive it sometimes! I think once everything is fixed this will run reliably with the proper maintenance. The previous owner did -10% maintenance.

Will be placing coils on order probably tomorrow or the day after.

Thanks again!

Oh the gremlins of the 8 haha... never seize to suprise me. :eyecrazyHmm..I've heard stuff about cold cranking, problem seems to be with the fuel pump from what I've heard. Something about some valve for retaining pressure? Not sure. When was last time that the fuel pumps were replaced?

Also, you should clean your MAF, might not help with this issue, but if they're dirty it's going to run like crap..and if it's real bad, go in to limp mode.

http://bmwe32.masscom.net/sean750/MAF_v12/MAFtroubleshooting.htm

And lastly, if you're going to replace your coils, you should check/replace other ignition parts..Plug boots, distributior caps, etc.

A Maf going south will throw a CEL doing initial idle and go off when the rpm's are raised, It will also start to work after the car has ran a minute or two, Easy to tell from the exhaust, One side getting warm/smoking, The other will be cold with no exhaust, Cold starts are in LHM and will sometimes go away when reved or engine temp is achieved, That's my experience from maf's going bad, When a maf is all gone, You'll certainly know, I would check the fuel pressure before just throwing away B$G money on fuel pumps? They work or they don't, I agree with Tx, I would look at the plugs, Very important! If they check out, Then buy some "new" coils based on all the parts recently replaced. Oh yeah, Got the right plugs in there? What brand and part#?

Thanks for the information. The distributor caps and rotors are brand new, so are the plugs. As for wires me and my dad tested them and they are fine.

Fuel pumps - I have no clue. Would the pumps really be going out at only 83,000km though? I've seen fords and gm's go a 200,000km before the pump went... my supra got up to 290,000km and the pump was still fine.

The mass airflows I cleaned out when the engine was apart for the intake gasket job. I'm really guessing this is a problem with spark. The plugs on the right bank of the engine were literally SOAKED, and the ones on the left damp... So the fuel is getting there, but not the spark.

A Maf going south will throw a CEL doing initial idle and go off when the rpm's are raised, It will also start to work after the car has ran a minute or two, Easy to tell from the exhaust, One side getting warm/smoking, The other will be cold with no exhaust, Cold starts are in LHM and will sometimes go away when reved or engine temp is achieved, That's my experience from maf's going bad, When a maf is all gone, You'll certainly know, I would check the fuel pressure before just throwing away B money on fuel pumps? They work or they don't, I agree with Tx, I would look at the plugs, Very important! If they check out, Then buy some "new" coils based on all the parts recently replaced. Oh yeah, Got the right plugs in there? What brand and part#?

The plugs are the correct Bosch F8LCR - the number on the small boxes is 7559..

Also when the car is up and running, it runs amazing! Just has hard time starting every second go at it. So I'm doubting it's anything but the ignition gremlins at work here.

Shit, really Jenya? Damn. You should read Johan's site, he was tackling a rough idle with his M70 for a while, he documented the steps he took to get rid of it (culminated with replacing the fuel pressure regulators). Also, do you get a CEL? Does the EML light come on when you turn ignition on and come off? Sorry if it's already been asked/answered >_>

http://bmwe32.masscom.net/dyn_menu.html#

Check the stuff applicable for M70 V12's under the engine catagory.

But yeah, I'm not sure man...fuel pumps are common culprits for M70 cars..perhaps you should go to a junk yard and get one on the cheap, swap it for a bank and see if it helps.

Jenya, you might look at the air temperature sensors, BMWs will go VERY rich if the temp sensor(s) is open or malfunctioning, or if the sensors go out of range when extremely cold it will cause the starting issues you have shown on the vid.

You may also try to floor the throttle before cranking and hold it there at the floor while cranking, it will easy the richness and is a way to clear a flooded engine.

There are temp sensors at the back of the intake manifold and on the rear water cross-over, they all should be hooked up and in working order.

paulmer
12-26-2008, 04:18 PM
Yeah, good idea MWrench. Also clean the coolant sensors, they are used to determine lots of stuff by the EML (calculate idle speed, etc).

I've replaced the ignition coils... the whole situation seems to have gotten better however every tenth time the car still starts like in the video I posted. It is also now pretty warm.

The parts that have been replaced in the last 5,000km are as follows:

- Spark plugs
- Both batteries
- Injectors cleaned and o-rings replaced
- Distributor Caps
- Distributor Rotors
- Fuel filters
- Both O2 sensors
- Pulleys/Belts/Tensioners
- Valve cover gaskets
- Intake manifold gaskets
- DK gaskets to manifolds
- DK's have been cleaned
- Starter
- Ignition coils

Also last night when I was driving the 'CHECK' light went on for about 30 minutes and then went away without coming on again for the rest of the night..

Probably a few things I am forgetting off top of my head, but what else could be causing this? I am running out of ideas.

The 4 temp sensors (2 air @ back of intake runners -2 water temp at coolant crossover pipe). These need to be in good working order so that the computers know exactly how warm or cold you engine is in order to set the F/A mixturte, timing, etc.
One of the 3 water temp sensors in the crossover is for the temp gauge in the dash (I would replace as well - just remember to get the correct one, Autohaus for instance sells those 2 as the same part number and this can also lead to inaccuracy since the EML sensor is more sensitive than the temp gauge one)

The car also did this today when I got into it after shutting it off for about 10 min.

Thanks, totally missed it.

So I need #8, 7, 5 + (9, 6 copper rings)?

Which one is the fourth one?

Yes, I hope you have small hands! Be sure and remove the cabin filter housing to allow more room to work.

There are only 3 back there. The other 2 sensors are the air temp sensors in the rear cover plate of the intake runners (#8 & #9 - one on each side)

If you don't remove it, you're not getting there!

Here is an updated video of what the car does when I try and start it.

and the other noise that comes from the engine bay (hissing/pumping sound from the brake booster)

At Rob Scott's wrench fest we figured out the problem as to why the car had trouble starting. One of the temperature sensors at the back was not plugged in so the EML was clueless about the engine temp during the start. Starts/runs like a dream now.

the eml was clueless about the oxygen sensor and thats why the car started like that. if the temp sensors are out the eml will assume the car is cold and not get values from the o2 sensor , therefore run way too rich.
if you had a diagnostic tool it would have told you all that info in less than 5 min. as you would have seen a bad reading in temp as well as it would tell you an error 'o2 sensor circuit'.

a tool like this one will save you tons of questions. and you will buy ingition coils, ignition leads, fuel ressure regulators and fuel filters.
only when you need them and not as part of your troubleshooting

not quite correct. The EML and DME temp sensors are an integral part of the engine management (fuel, mixture, timing). Having one or more unplugged (remember 1 is EML, 1is DME's, & 1 is temp gauge) will really confuse the computer and will cause the syptoms as shown in the video.
The same starting problems can also be attributed to faulty CPS, fuel pumps, etc., but these were not the case.

basically a different way of repeating what i stated.
The same starting problems can also be attributed to faulty CPS, fuel pumps, etc., but these were not the case.
that is why a diagnostic tool is an absolute must
otherwise one will buy two ignition coils, two cps sensors , a fuel pump, fuel filters , fuel pressure regulator, o2 sensor, because that would be the things you guys would recommend to replace.

Video of smooth running please?

Hey guys, I live just outside Edmonton city limits to the sw around Devon area. I'm still learning about this car but have so far been able to address all the problems ( with some help from the great people on this forum ) and repair them myself. Like I said I'm still learning but I'm handy with a wrench and willing to help out anyone in the area. So feel free to drop me a line if your having troubles. Glad to hear you solved the hard start problem Jenna.

Cheers,

Have you joined the Alberta 8's yet? They had a WrenchFest in Calgary last Saturday/Sunday.

I tried to make the fest but was working in Calgary all week and drove home to Edmonton fri night (Had the work truck down there), worked on the car all weekend, but she is all back together and running, complete stereo redo wires speakers etc, new hydraulic hoses, filter, cleaned the years of oil and grime from under the oil filter housing along the frame rail. It sure cleand up nice. Now I just need afew items from the wuff man. He he he any luck with those ends yet ;) Ready for the next meet though, if work doesn't get in the way again lol.

Cheers,
Andrew from AB
