Okay, my turn for help

I have a '77 that I bought from another member. It has a completely rebuilt engine. It was all apart when I got it. Now I can't get it to start. Got everything to work except the injectors. Is there a relay to the ECU? I've got fuel pressure and spark. Even the cold start injector won't squirt.

ECU could be bad... or no power going to the ECU that runs the injectors... or the pick up sensor??? You need to check all the wires, make sure that it's good... good luck...

the FI system does have a relay. should be the only one under the hood thats out in the open, just a square 4 pin (i think) relay plug.

Have you already done the noid light test to see if there's a signal to the injectors? Even newly cleaned, if the injectors have sat for awhile, they might all be stuck. That was the case with mine when I first fired it up after the rebuild. Just a thought.

I found some good info at Alanticzcarclub. The relay is under the dash. Now I can hunt the problem down I hope. Since it was a runnig car before tear-down I think it's a wire I overlooked. I will let you know. Thanks guys!
