SYMPTOM INDEX

STARTER RELAY

  1. Remove starter relay from battery junction box. Battery junction box is located in left side of engine compartment, in front of strut tower. Check relay continuity. Continuity should exist between relay terminals No. 85 and 86, and between relay terminals No. 30 and 87a. (Scheme 12) Continuity should not exist between relay terminals No. 30 and 87. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
  2. Using a jumper wire, apply battery voltage to relay terminal No. 85. Using a second jumper wire, ground relay terminal No. 86. Continuity should now exist between relay terminals No. 30 and 87. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay at this time.

STARTER SOLENOID

Remove starter from vehicle. See STARTER MOTOR under REMOVAL & INSTALLATION. Check resistance between starter motor ground terminal and solenoid case. Resistance should be about .95 ohm. If resistance is not about .95 ohm, replace starter solenoid.

STARTER MOTOR

WARNINGWhen performing maintenance on starting system, be aware that heavy gauge leads are connected directly to battery. Ensure protective caps are in place when maintenance is complete.
