    We’re BOTH fuses good?

    DTC code 18 is NOT for "injector circuit BREAKER", it’s for "injector circuit". That means the voltage on one (or more) of the 8 injector circuits is not correct.

    - Each injector connector should have 12 volts on the pink wire, with key on. Check with a volt meter.

    - Each injector should have a resistance of ~12-16 ohms. Measure resistance across the 2 injector pins with an ohm meter, connector off the injector.

    - The PCM supplies a ground to fire each injector. The best way to check this, with the engine running, is a noid light.

    PCM/injector wiring diagram (94 is the same as 95):
