PCM And Three 32-Way Connectors
-
If voltage remains at or near battery voltage during the entire 5 seconds, turn the key off. Remove the three 32-way connectors from the
PCM. Check 32-way connectors for any spread terminals or corrosion.
7. Remove test lead from the coil positive terminal. Connect an 18 gauge jumper wire between the battery positive terminal and the coil positive
terminal.
Special Jumper Ground-to-Coil Negative Terminal
8. Make the special jumper shown. Using the jumper, momentarily ground the ignition coil driver circuit at the PCM connector (cavity A-7). A
spark should be generated at the coil cable when the ground is removed.
9. If spark is generated, replace the PCM.
10. If spark is not seen, use the special jumper to ground the coil negative terminal directly.
11. If spark is produced, repair wiring harness for an open condition.
12. If spark is not produced, replace the ignition coil.
