Start Signal System Test
- Locate ECM harness connector. ECM is located behind glove box. Measure voltage between ground and ECM harness connector terminal No. 43 (Black/Yellow wire). Turn ignition switch to START position. Battery voltage should be present in start position ONLY. Zero volts should be present in any other ignition switch position. If voltage is not as specified, go to next step. If voltage is as specified, system is functioning properly.
- Turn ignition off. Check Green fusible link located in fusible link holder next to battery. Check 7.5-amp fuse located in fuse box under left instrument panel. Repair or replace as necessary. Also check continuity between ECM and ignition switch, and between ignition switch and battery. See Fig 1
. Continuity should exist. If continuity does not exist, repair open harness or connectors as necessary.
