New to this forum and I have an 84 Fiero 2m4 four speed. It will not start. Here is the background: I bought this car 3 weeks ago. Test drove it, ran fine but weak, CEL was on. Bought it anyways. Got it home (had to tow it, half way home the throttle cable broke, replaced it and transmission link cables) and took it for a test drive, started and ran but cut off randomly. Checked CEL code, was bad PROM chip install. Checked it out and there was no PROM chip in the ECM, was a replacement aftermarket ECM. Found a guy off this site and ordered the chip. Put it in and new air filter and plug wires. Now, no start at all. CEL light dose not come on at all. I have spark but the fuel injector is not opening. Checked Fuel injector wiring, +12V to injector, +12V to ECM Pink/Black wire both with key on. Have +12V to orange wires at ECM. Fuel pump dose not come on with key, dose come on with oil pressure, and is working correctly. Replaced Injector and fuel filter just to be shore. Just want to see if there is any other wiring I should check or is the ECM my next step?
