Test E: The Starter Spins But the Engine Does Not Crank
PINPOINT TEST E: THE STARTER SPINS BUT THE ENGINE DOES NOT CRANKE1:
Normal Operation
Under normal operation, power is supplied to the starter relay coil through the key switch and circuit 33 (WH/PK). A ground is supplied through circuit 329 (PK) and the PCM. When the starter relay coil is energized, the relay contacts close. This allows power to be supplied from central junction box (CJB) fuse 113 (30A) thought circuit 2037 (RD) to the relay contacts. Power then flows through circuit 113 (YE/LB) to the starter solenoid. The solenoid is grounded at the starter motor. Energizing the starter solenoid will engage the starter drive into the ring gear. It also closes the solenoid contacts allowing power directly from the battery to energize the starter motor to start the engine.
Possible Causes
- Worn or damaged starter motor
- Damaged flywheel ring gear
