Pinpoint Test A: The Engine Does Not Crank And The Relay Does Click

WARNING: This page is about a different car, the 2005 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

A1 CHECK THE VOLTAGE TO THE STARTER RELAY
- Measure the voltage between starter relay pin 30, circuit 1523 (DG) and ground.

- Is the voltage greater than 12.5 volts?
- Yes : GO to A2.
- No : REPAIR circuit 1523 (DG) for an open. TEST the system for normal operation.
A2 CHECK THE VOLTAGE TO THE STARTER MOTOR SOLENOID
- Measure the voltage between starter motor solenoid positive terminal and ground.

- Is the voltage 12.5 volts or greater?
- Yes : GO to A3.
- No : REPAIR circuit 2037 (RD) for an open. TEST the system for normal operation.
A3 MANUALLY JUMP THE STARTER MOTOR
- Connect one end of a fused (15A) jumper wire to the positive terminal of the battery and touch the other end to the starter solenoid S-terminal.

- Does the starter solenoid engage?
- Yes : GO to A4.
- No : INSTALL a new starter. TEST the system for normal operation.
A4 TEST THE STARTER MOTOR RELAY
- Carry out the relay component test on the starter motor relay. Refer to the RELAY COMPONENT TEST .
- Does the starter motor relay test good?
- Yes : REPAIR circuit 113 (YE/LB) for an open. TEST the system for normal operation.
- No : INSTALL a new starter motor relay. TEST the system for normal operation.
