Fiero 3800 swap harness5/4/2023 ![]() ![]() I've hooked up a fuel pressure testing gauge and validated that it has healthy fuel pressure before starting, and when it starts. So cylinder 1 has injector 1, cylinder 2 has injector 2, etc. I've validated that all 6 injectors are wired from their respective cylinder, to the injector wire # on the PCM. That led me to thinking its fuel related. I went so far as to keep the engine running with starting fluid for as long as I wanted, which means it must have spark to keep running. To trouble shoot this, I've validated that it has spark. I can crank it over and it fires right up, but then dies within 1-2 seconds. However, the danged thing wont run for more than a second. It cranks, all sensors I can think of seem to read correctly in HP Tuners VCM scanner. The car has a healthy cam in it, 42lb injectors, N* MAF, N* TB. I am attempting to control the engine with a 2003 PCM running the S/C OS. I am about done wiring up a 2003 3800 S/C swap into an 86 fiero. Hopefully someone can help me out, or point me in a good direction to look. ![]()
