Troubleshooting: 2.0 won't stay running Options

[Nate]

Hey everyone! Hope you are all preparing for a nice thanksgiving.

Wanted to see what ideas you guys had about my original FI 2.0 from 73. Some of you may have seen a few other threads of mine but I'll give a little synopsis. I rebuild the motor in my garage. New Pistons and cylinders, all new bearings, lifters. Ground crank and cam. Heads rebuilt by a reputable shop. For the rest of the car. New fuel lines, cleaned and coated fuel tank. New fuel filter. Cleaned and flow matched fuel injectors. Rebuilt distributor. Tuned dwell angle and set static timing.

So I've done all of that and the car won't stay running. It'll start and run for 20 seconds with a high idle (approximately 2500 rpm's) and then it will die even if I'm feathering the throttle.

I'm looking for ideas as to what and how to troubleshoot the car. IF this car was a person I'd strangle it to relieve my frustration.

P.S. I went through the ecu harness and ohm'd everything out and there are no shorts in the wiring and the grounds are solid. I also replaced the throttle position switch and have that set up according to the book and have messed with the idle mixture knob a bit.
Anyone have any ideas on where I should go from here?

Thanks and I wish everyone a good safe holiday.

Throttle body and TPS are working and busted according to the book.
FI relays wouldn't be a problem if I'm getting fuel through the injectors right?
I'm getting good spark and I don't think that would be the case of the trigger points were bad. Or maybe not?
I will try disconnecting the AAR hoses in case it is stuck closed.
I'm starting to think that the ECU may be to blame so I may be trying to see if someone has a working one I can borrow to troubleshoot.

As always, thanks for the ideas and help. It is always appreciated.

Trigger points are associated with injectors not spark plugs. One set of points work with one bank. The other set works with the other bank. How did you test the injectors? Did you test them in the car or did you do something else?
