Obviously faulty fuel pump, horribly clogged injectors, clogged fuel filter . Bad crankshaft position sensor. The usual. Vehicle is a 1992 3.1 mpfi Che vrolet Lumina. Died one day as I shifted from park to drive. Runs with star ter fluid, and funky gas vapor contraption my friend hooked up to the intak e for a short time (2 seconds, it's very funky). No smell or indication of gas when cranking.
My understanding is these injectors receive a pulse, but not constant power , that opens them. I ohmed the 2 injectors that could be, 12 ohms. I ohmed as much as I could and it checks out (trust me, I'll explain if I have to), therefore the injectors themselves do not seem to be the problem.
Computer has no stored codes. Nothing has ever been done to this car. But I payed some idiot to replace the ignition module about 4 years ago. Whenev er it rains and the car sits for 4+ hours, it won't start until I put a spo t lamp or heat gun on my wires/coil packs for usually a few minutes. There is spark and that should rule out the module. But I was told by one source that the ignition module is what supplies pulses to the injectors at the very beginning of a start.
Could a sensor be responsible for all this? Fuses and relays seem good. Is there some input the computer isn't getting that prevents it from firing in jectors, and doesn't store a code?
Just curious if it was possible to switch key to ON and either supply a con stant voltage or pullse to the injector/s to see if the injectors will open ?
