Pinpoint Test 1: The Engine Does Not Crank
PINPOINT TEST 1: THE ENGINE DOES NOT CRANK
Normal Operation
Constant power is supplied to the starter relay on circuit (L/R). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL (automatic transaxle) or clutch depressed, clutch cutoff switch (manual transaxle), the PCM provides power to the starter relay on circuit (GY/V). The PCM provides ground to the starter relay coil on circuit (Y) to the starter relay. When the coil of the relay is energized, it sends power to the starter motor on circuit (BR/G).
Possible Causes
- Battery
- Ignition switch
- Starter relay
- Anti-theft system
- Wiring, terminals or connectors
- Powertrain control module (PCM)
