Background:

1.8L FI w/ Stock distributor

I Recently removed engine to sort various problems and reinstalled. I can get the car to start and idle per spec and Dwell is w/in spec (45).
BUT.....

When I jump in the car and blip the accelerator pedal (not significant RPMs about 3500-4000) the car dies. However, when I hit the throttle cable from the engine bay it's fine... no stalls.

What would cause this?

- Badly positioned or tangled accelerator cable?
- Funky distributor cam messing with dwell?
- Vacuum issue?
- Air Flow Meter?


When I go to restart, it won't fire and I have to reset timing and start the process all over.

Any troubleshooting steps or tips appreciated!

What do you mean by this, exactly?



If the engine runs normally when operated manually, then I would focus on the throttle cable, but the only reason I could see that causing the car to die would be if it were creating/interrupting some kind of ground-path that's screwing with the ECU.

Did you reinstall the ground strap on transmission?

Check all your grounds and try connecting a jumper cable between the engine block and the negative terminal on the battery, then check it again.

I appreciate the response!

When the car stalls out and dies. It won't start again, unless I bring everything back to TDC and static time again. This may by a fallacy on my part, but that's what I've done to get her running again.


Transmission ground strap is in place and grounds are good, but will double-check.

Maybe it's an issue with TPS??
