:dunno At this point i am lost
Car has been driving Perfectly for months.. (Til the 5th when my gas gauge went dead..could it be related)
Driving home yesterday the car just cut off @ a redlight.
I cranked and cranked and cranked and finaly It starts.
Weird!!
THen a hour later when i finally made it 1 blk away from my house it cuts off again and this time doesnt restart.
Coil , Wires , PLugs, all fine.
Went straight to yanking the fuel cover off under the seat !! NO noise
Replaced the pumpand sender from a running e30 DD NOTHING
CHeck relay assumed the fuel pump relay is dead
SO i searched online and checked the manual
tried jumping the 30 prong with the 87 prong then fuel pump cuts on stays on. PUMP WORKS
Got new Relay. from parts store. NOTHING. Same thing. FUel pump makes no noise SO unless i got a faulty relay then something else is wrong. TRIED STARTING CAR WITH JUMPER WIRE ON..... NO START ........
Tried a New ECU..nothing!

SO i searched again In Haynes is says check fuseable link 6 inches from battery on thin blk wire. NOTHING its looks fine and normal. Just to make sure I bypassed the link with a wire and still nothing.
WTF is causing this problem. Search online on this Forum and looks like everyone who has ever attemted this post get no where!! NO one gives them an answer and the thread ussauly subsides to jokes and offtopic BS.

WHat else to do besides giving it to the dealership.
What does your Bentley say obviously my Chilton/Haynes isnt sufficent enough.
^^ problem is as stated above .. WHat is next..?
