1997 Bonneville sseimotor swap help
I got a motor out of a 1997 bonneville ssei and i put it into a totally dfferent car. I wont saw what kind cause you'll probably laugh your *** off!! Anyhow, i got everything hoooked up, the motor runs perfect for about 5-6 seconds and then just cuts out. I checked both fuel and ignition and both are working normally (from what I can tell). Tried checking vaccuum, getting about 18hg, fuel pressure is at 50psi, and getting a strong spark. Does anybody out there have any ideas what might be going on????

If memory serves me, I think that the PassKey module needs to send a certain code to the PCM otherwise the PCM kills the engine after a few seconds.
Do you have the passkey module?

Unless you've chipped the PCM, a simple ground won't cut it. If you don't have the PassKey module, try these directions to emulate one:

The PCM requires a modulated signal from the PassKey module; the circuit on that page emulates the proper signal.

hmm.... ill give it a shot. Do you think you might have a larger photo of the completed part. Ive never built anything like this and a good photot might be really helpful!! If i dont feel to comfortalbe with building this myself, do you think you might be able to build me one? How much would you charge me?

I don't run that other page, so I don't have any photos of the completed project. However, the schematic (which is on that page) is far more important than how the board looks in a photo.
Building the emulator wouldn't be too dificult. If you don't feel comfortable putting it together, I think there are several companies on the web that make PassKey Defeat systems.

For the record, using the component values on http://www.fieroaddiction.com/passkey.html produces the following results:
R3 @ 3.9k and R2 @ 22k = 53% duty cycle square wave at 29 Hz (+/- 7%)
R3 @ 1k and R2 @ 14k = 50% duty cycle square wave at 44 Hz (+/- 7%)
Change the values at your own risk
