Did you swap the FD yet?

Ha, nah. That thing has 14000 miles on it.

Hell yeah that was me! Twas nice to meet you. I got the proper size key for the transmission, fluid has been changed and we're going to be putting it in the car next weekend (hopefully)!

And it ROARS to life!



but with a horrible idle that sometimes doesn't exist, and so it dies, and then it won't start again, at least for 15 minutes or so....

We replaced the fuel rail and lines from the new engine with the one from the original engine and still having some fuel (seemingly) issues. Our plan is to test the transfer pump and then main fuel pump this Saturday. Wish us luck!

We were trying to check the timing but the thing won't run for more than 5 seconds and only if you don't touch the throttle. If you touch the throttle then it shuts right off.

Any ideas anyone?

Throttle position switch? Air flow meter?

I believe if the AFM is toast, you can unplug it and the car will idle roughly but do nothing else. I've ran with a bad transfer pump before, the car will run but will struggle. You should be able to hear it prime when you first turn the key. Other than that you can jumper the fuel pump relay to hear the main pump.

The TPS only has an idle switch and full throttle switch, it's not like a modern TPS that tells position through the whole range.

If the car starts, the timing isn't too far off, but you can double check that the rotor is lined up with the mark when #1 is at TDC.

Double check all of your vacuum connections.

Curious to see. My car is having these symptoms and I have replaced all of these things to no avail.

[gettinscurvy]

I shall be double-checking vacuum, fuel pumps and I guess unplugging and plugging my afm to see if anything changes. Thanks guys!

[gettinscurvy]

vacuum was ok, fuel pumps checked and the transfer pump was dead. got a new one from the pick-n-pull yard for $27 and it works great, but it still doesn't start consistently and when it does it immediately dies.

New one



Old one next to new one

When you checked the vacuum lines, did you pull off the intake boot and check it for cracks? Have you changed the fuel filter? This should be done just for general maintenance anyways.

Make sure all the grounds for the engine are clean, that can do some weird things.

Do you have a spare fuel pressure regulator that you can swap in?
