Is your car OBD1 or OBD2?

I think you need to align the EWS/ECU. Its the only thing I can think of right now.

I have an OBD II car, but have the computer and wiring harness for the OBD I ... I did all the re-wiring that you are supposed to do, but nothing...the EWS gets cut as not to send a kill signal...I was under the impression that when you are switching to the OBD I from the OBD II you didn't have to get them aligned...am I wrong?...thanks for the insight though

The other thing to check out would be that you have your power hooked up right. There should be three cables going to your positive terminal. One goes to the alternator/starter, one to the body power box, and one provides power to the rest of the engine. If you have a multimeter you can check and make sure you are getting power to the starter as well. You should always have 12v on the red wire. Also, check the ignition switch to make sure the black/yellow (on mine) wire is getting power when you turn the key to start.

Does the key, the computer, the ignition etc... whatever things that need to match up for the keys match up? With chipped keys (and I am no expert and don't really know how any of it works) I think all the stuff has to match so that it can send the proper signal otherwise it has the OEM anti-theft stuff that won't allow you to start the car... I think. at least it may be something to look into if you haven't already. goodluck.

EDIT: ummm I am a little behind the times I guess thats what you meant by the EWS huh?? ...well goodluck anyway

Ive done quite a few write ups in this section and on bimmerforums.com for OBDII chassis to OBDI, ews delete. You should recheck the threads as they come with diagrams, picures, and text.
