I just want to share with others that have this relatively stock setup, for originality sake. I have a 82 and 83. The 82 would not start, fuel pump would prime, I had spark, ecm okay, no codes stored. I read through the factory manual and it only would take me to a dead end. I read the vette message boards, use a noid light, check the distributor, check the oil pressure gauge, check the engine temp sensor, check the inject fuses, check the fuel pump relay, something must be bad. My problem, both injectors frozen shut, banged on them with a wrench, fired right up, this was after two weekends of troubleshooting. If you ever have a no injector pulse but fuel pressure, and priming your self fires it right up, its the injectors.
