Car Forum / Pontiac / Pontiac Fiero / April 2005a little help please
Greetings ! The car - 86 Fiero 2M4 The problem - I just uncovered it after the Winter. Put in the battery and had a short.Reconnected some wires and tried to fire it up. Engine turns over, it has spark and there's gas up to the throttle body however the injector isn't squirting. I put some gas down the throat and it'll run until it burns of. Any help or ideas are appreciated ! Thanks in advance ! > Greetings ! > The car - 86 Fiero 2M4 [quoted text clipped - 4 lines] > it burns of. Any help or ideas are appreciated ! > Thanks in advance ! Sounds like the injector has failed, or the power to it has failed. Explain what you mean by "short". The way this inector works is that 12V battery power is provided at all times via the ignition switch and the INJ fuse. To complete the circuit and open the injector, the ECM provides a ground using a transistor inside the ECM case. You can use a meter to check for power one one of the two wires at the injector when the key is in RUN. If no power, check the fuse. Use a meter to check the fuse, those blade-type fuses commonly fail by cracking and will look perfectly good even though they're bad. Alternately, you can buy what's called a "noid light" or injector tester, it's basically a lightbulb in a plastic case that plugs into the injector harness connector. It will blink while you're cranking. If it doesn't blink then you check the wiring.
