Q&A

my car wont stay started for more than a couple revolutions. it only fires occasionally during this. i changed a coil pack, all the plugs and wires, ran fuel injector cleaner, and checked all the regular fluids and stuff. the alternator and battery are fine, it seems to be a fuel problem, possibly too much. my question is, would a fuel filter cause this? i ran a diagnostic and the check engine light said,* ** * ** * **. i'm guessing that is 1 2 or 12. but i don't know what do do with this code.
