    Injectors not firing

    So what should I check? Crank and cam sensors are both new and verified working. Fuel pump works because it primes but the injectors just won't fire. This is intermittent, I went out to try and see if I had spark and car decided to start this time and doesn't want to cooperate. Input?

    you check injector ground?
    your coils good?
    check if your crank and cam mixed up? only counts if odb1 when your odb2 you cant mix them up

        OBD1, Injector ground was just checked, its good. I took it apart and cleaned and brushed it to make sure. Coils were just replaced and I checked all 6 before putting them in, verified good. Crank and cam aren't mixed up because car runs, just sometimes will die and won't start for a while.

            It seems like the case, but after replacing it almost 4 times and checking it ever time I replaced it, it reads good resistance.
