Normal Operation
Under normal operation, constant power is supplied to the starter relay on circuit 1050 (LG/VT). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL, the TR sensor provides power to the starter relay coil on circuit 33 (WH/PK) and the PCM provides ground to the starter relay coil on circuit 1419 (LG/YE). When the coil of the relay is energized it sends power to the starter motor on circuit 113 (YE/LB).
Possible Causes
An engine that does not crank can be caused by the following:
- Battery.
- Fuse(s).
- Ignition switch.
- Starter relay.
- Anti-theft system.
- Circuitry.
