Test B: Engine Does Not Crank & Engine Does Not Click
WARNING: This page is about a different car, the 2004 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before beginning this test, ensure transmission is in Park or Neutral.
- Check The Starter Motor Relay Coil For Voltage
Disconnect starter motor relay. Turn ignition switch to START position. Measure the voltage between the starter motor relay connector terminal No. 86 (Tan/Red wire) and ground while holding the ignition switch in the START position. See Figure . Is the voltage greater than 10 volts? If yes, go to step 5 . If no, go to next step. - Check For Voltage At Fuse No. 33
Turn ignition off. Disconnect fuse No. 33 (10-amp). Turn ignition switch to START position. Measure the voltage between the Central Junction Box (CJB) fuse 33 (White/Pink wire) and ground while holding the ignition switch in the START position. Is the voltage greater than 10 volts? If yes, repair Tan/Red wire between fuse No. 33 and starter relay. See WIRING DIAGRAMS . Test the system for normal operation. If no, go to next step. - Check Light Green/Violet Wire For Voltage
Turn the ignition off. Disconnect ignition switch connector. Turn ignition on. Measure the voltage between the ignition switch connector terminal B+ (Light Green/Violet wire) and ground. See Fig 1 . Is the voltage greater than 10 volts? If yes, go to next step. If no, repair Light Green/Violet wire between fuse No. 7 in BJB and ignition switch. See WIRING DIAGRAMS . Test the system for normal operation. - Check The Ignition Switch
Carry out the ignition switch component test. See appropriate STEERING COLUMN SWITCHES article in ACCESSORIES & EQUIPMENT. Does the ignition switch test good? If yes, repair White/Pink wire between ignition switch and fuse No. 7. See WIRING DIAGRAMS . Test the system for normal operation. If no, install a new ignition switch. See appropriate STEERING COLUMN SWITCHES article in ACCESSORIES & EQUIPMENT. Test the system for normal operation. - Check The Relay Ground Circuit For An Open
Turn ignition off. Measure the voltage between the starter motor relay connector terminal No. 85 (Light Green/Yellow wire) and terminal No. 86 (Tan/Red wire). See Figure . Is the voltage greater than 10 volts? If yes, install a new starter motor relay. Test the system for normal operation. If no, go to next step. - Check Light Green/Yellow Wire
Turn ignition off. Disconnect PCM connector C176a. Measure the resistance between the starter motor relay connector terminal No. 85 (Light Green/Yellow wire) and PCM connector C176a terminal No. 4. See Figure and Fig 2 . Is the resistance less than 5 ohms? If yes, install a new PCM. Test the system for normal operation. If no, repair Light Green/Yellow wire between starter relay and PCM. See WIRING DIAGRAMS . Clear the DTCs. Test the system for normal operation.
