Injector Circuit
- Turn ignition off. Disconnect suspect fuel injector wiring harness connectors. Turn ignition on. Measure voltage between connector terminals. If voltage is 11-14 volts, go to next step. If voltage is not 11-14 volts, check fuse. If fuse is okay, repair Yellow wire in fuel injector circuit.
- Leave fuel injector connector disconnected. Using an ohmmeter, measure resistance between fuel injector terminals. If resistance is not 10-14 ohms, replace fuel injector. If resistance is 10-14 ohms, fuel injector is okay and testing is complete.
