Trouble Shooting Hints
On all models, note condition of SECURITY indicator light. If indicator stays on or flashes continuously, see ANTI-THEFT SYSTEM in appropriate ACCESSORIES & EQUIPMENT article. Check starter solenoid terminals and battery grounds. Check for proper installation of aftermarket electronic equipment. Perform self-diagnostic system test, to be certain no trouble codes are stored in PCM memory which may lead to misdiagnosis. See the TESTS W/CODES article for Riviera, or the TESTS W/CODES article for Aurora in ENGINE PERFORMANCE section.
Check 60-amp IGN-3 fuse in rear maxi-fuse block No. 2. See COMPONENT LOCATION table, for location. If fuse is open, check for a short to ground in Yellow wire between ignition switch connector terminal D1 and starter enable relay connector terminal C1. Check for a short in Purple wire between starter enable relay connector terminal A2 and starter solenoid connector terminal "S".
