WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, and 2003 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
- Check The Voltage To The Starter Relay
Measure the voltage between the starter relay connector terminal No. 30 (Red wire) and ground. See Fig 1. Is the voltage greater than 12.5 volts? If yes, go to next step. If no, check fuse No. 113 (30-amp). If fuse is okay, repair Red wire between battery and starter relay for an open. See WIRING DIAGRAMS . Test the system for normal operation. - Check The Voltage To The Starter Motor Solenoid
Measure the voltage between the starter motor solenoid positive terminal "B" and ground. See Fig 2. Is the voltage 12.5 volts or greater? If yes, go to next step. If no, repair Red wire between battery and starter for an open. See WIRING DIAGRAMS . Test the system for normal operation. - Manually Jump The Starter Motor
Connect one end of a fused jumper wire (15A) to the positive terminal of the battery and touch the other end to the starter solenoid "S" terminal. See Fig 2. Does the starter solenoid engage? If yes, go to next step. If no, install a new starter. See STARTER MOTOR under REMOVAL & INSTALLATION. Test the system for normal operation. - Test The Starter Relay
Perform the relay component test on the starter relay. See STARTER RELAY under COMPONENT TESTS. Does the starter relay test good? If yes, repair Yellow/Light Blue wire between starter relay and starter solenoid for an open. See WIRING DIAGRAMS . Test the system for normal operation. If no, install a new starter relay. Test the system for normal operation.
