  4. Turn ignition off. Disconnect a fuel injector harness connector. Turn ignition on, with engine off. Using a test light connected to battery voltage, probe the ignition 1 voltage supply circuit of a fuel injector. Does test light illuminate? If yes, go to step  6. If no, problem is intermittent. See TROUBLE SHOOTING - NO CODES article.
  5. Turn ignition off. Disconnect a fuel injector harness connector. Turn ignition on, with engine off. Probe the ignition 1 voltage supply circuit of the fuel injector with test light connected to a good ground. Does the test light illuminate? If yes, go to DTC P0341. See appropriate SELF-DIAGNOSTICS article. If no, go to step  7.
  6. Test the ignition 1 voltage supply circuit of each fuel injector for a short to ground. Replace the fuse. After repairs, go to step  8.
