Testing Honda Prelude Ignitors Q. Hello Vincent, I was wondering if there was a way to check if the Ignitor in a Honda Prelude was bad or not. It is a 1994 with 45,000 miles and the engine just died out on me at a stop light. I had a hard time starting it back up and now have intermittent starting problems. Any help would be great. Thanks, Glenn

A. Here is the test procedure for you Glenn:

1. Remove the distributor cap, the distributor rotor, and the inner cover.

2. Disconnect the BLACK/YELLOW, GREEN, YELLOW/GREEN, and BLUE wires from the ICM.
3. Turn the ignition switch ON. Check for voltage between the BLACK/YELLOW wire and chassis ground. There should be battery voltage.
   • If there is no battery voltage, check the BLACK/YELLOW wire between the Ignition Coil and the ICM.
   • If there is battery voltage, go to step 4.

4. Turn the ignition switch ON. Check for voltage between the GREEN wire and chassis ground. There should be battery voltage.
   • If there is no battery voltage, check the:
   • Ignition coil.
   • GREEN wire between the ignition coil and the ICM.
   • If there is battery voltage, go to step 5.

5. Check the YELLOW/GREEN wire between the PGM-IG ECM and the ICM.
6. Check the BLUE wire between the tachometer and the ICM.
7. If all tests are normal, replace the ICM.
