  14. Did the fuse in the jumper open? If so, go to step  23 . If not, go to step  24 .
  15. Turn OFF the ignition. Disconnect the PCM. Connect a test lamp between the crank voltage circuit of the PCM and a good ground. Turn the ignition to the Start position. Does the test lamp illuminate? If yes, go to step  26 . Go to Step  18 .
  16. Turn OFF the ignition. Disconnect the BCM. Connect a test lamp between the crank voltage circuit of the BCM and a good ground. Does the test lamp illuminate? If so, go to step  27 . If not, go to step  19 .
  17. Turn OFF the ignition. Disconnect the IPC. Connect a test lamp between the crank voltage circuit of the IPC and a good ground. Does the test lamp illuminate? If so, go to step  28 . If not, go to step  20 .
  18. Test the crank voltage circuit of the PCM for an open or high resistance. Did you find and correct the condition? If so, go to step  38 . If not, go to step  29 .
  19. Test the crank voltage circuit of the BCM for an open or high resistance. Did you find and correct the condition? If so, go to step  38 . If not, go to step  29 .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
