hey, my car wont start unless i disconnect the battery, then i have to put my key in and turn the ignition to on then connect up the battery then when i turn the key it starts, when i dont do this the lights just come on and nothin else happens it dosnt even try and turn over , any help appreciated

i forgot to say that there is a clickin noise too when i turn it on

If the clicking sound is from the starter the cause could be low battery voltage. You can have the battery tested at most any auto parts house (Advance, Auto Zone, etc).

no everytime i disconnect the battery its starts first time, the battery is fully charged i got the car diagnosed and the fault comin back said its the immobilisor , how can i get this fixed?

Was the diagnosis a fault in the EWS or the immobilizer? The immobilizer is essentially a command detonated fuse in the primary wire to the starter and I quess I don't know if a 95 has one. In an accident the SRS fires the fuse to prevent starter operation. If this car has an immobilizer, a quick proof of it being the cause would be to jumper around the fuse. If that fixes it replace the immobilizer.

If the fault is in the EWS more diagnostic information would be needed to determine the fix.

thanks for the info, no its not the ews the diognostic showed it was the immobiliser

where can i find that fuse ? the ews is sweet , the diagnostic information showed up a fault with the immobilizer , when i get the car started by removing the battery then connecting it it would drive all day long until i take out the key , surely if it was the fuse it wouldnt start , but i will look there , can u please tell me where this is?

From memory on an E36, there are two positive cables that connect to the battery. One has a lump in the cable that contains the immobilizer fuse. While that fuse could have a high resistance, I don't see how that could be temporarily fixed by disconnecting the battery before start. It sounds to me like the fault is in the EWS or DME, in which case a hard reset might work. But a temporary jumper around the immobilzer would quickly tell if it is at fault.

where is the dme

how do i do a hard reset?

the car has no remote and the car was lyin for 3 months and the battery died , im thinkin it maybe the anti theft system , is there a fuse or relay that i could pull to disarm?

how do i do a hard reset?
That's what disconnecting the battery does.
the car has no remote and the car was lyin for 3 months and the battery died
Did you replace the battery? If not does it charge up to and remain at 12.6-12.7v under load (for example with the parking lights on)?

yeah i changed the battery , sometimes the car does start without disconnecting the battery and yes i did replace the battery

i forgot to mention that i am using the key without the chip in it to start the car , it is the grey key i dont have the original key , do u think this what mite be wrong?
