Test A: Engine Does Not Crank & Relay Clicks
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Verify battery condition. If battery is okay, measure voltage between each Red wire at starter motor relay and ground. Battery voltage should be present at one Red wire only. If battery voltage is present on one Red wire, go to next step. If battery voltage is not present on either Red wire, repair or replace Red wire between battery and starter motor relay cable. Check system operation.
- Measure voltage between starter motor solenoid "B" terminal and ground. See Fig 1. If battery voltage is present, go to next step. If battery voltage is not present, clean and tighten battery and solenoid terminal connections. If battery voltage is still not present, replace positive battery cable. Check system operation.
- Using jumper wire, connect one end to positive battery terminal and with other end, momentarily touch starter solenoid "S" terminal. See Fig 1. If solenoid engages, go to next step. If solenoid does not engage, replace starter motor. See STARTER MOTOR under REMOVAL & INSTALLATION. Check system operation.
- Using heavy gauge jumper wire, connect one end to positive battery terminal and with other end, momentarily touch starter solenoid "M" terminal. See Fig 1. If starter spins, go to next step. If starter does not spin, replace starter motor. See STARTER MOTOR under REMOVAL & INSTALLATION. Check system operation.
- Disconnect solenoid relay switch connectors. Disconnect starter motor solenoid connectors. Measure resistance of Red wire between starter motor relay and starter solenoid. If resistance is less than 5 ohms, replace starter motor relay. If resistance is 5 ohms or greater, repair or replace Red wire between starter relay and starter solenoid. Check system operation.
