WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
- Measure and record the battery voltage at the battery terminals. The voltage should be between 12.6 and 15.0 V.
- If not within the specified range, refer to Charging System Test .
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ω between the starter motor case and the negative terminal of the battery.
- If greater than the specified range, test the battery negative cable for an open/high resistance.
- Verify that a test lamp illuminates between the starter solenoid B+ circuit ring terminal X2 and ground.
- If the test lamp does not illuminate, test the battery positive cable for an open/high resistance.
- Remove the drive belt. Refer to the appropriate procedure listed below.
- Drive Belt Replacement for the 2.0L (LNF) engine
- Drive Belt Replacement for the 2.2L (L61) and 2.4L (LE5) engines
- Rotate each pulley by hand. Verify that none of the engine accessories or idler pulleys are seized.
- If any components are seized, replace the appropriate component.
- Attempt to rotate the crankshaft using a breaker bar, flywheel turner, or other suitable tool. Verify that the engine is not seized.
- If the engine is seized, refer to the appropriate procedure listed below.
- Engine Will Not Crank - Crankshaft Will Not Rotate for the 2.0L (LNF) engine
- Engine Will Not Crank - Crankshaft Will Not Rotate for the 2.2L (L61) and 2.4L (LE5) engines
- If the engine is seized, refer to the appropriate procedure listed below.
- If all circuits test normal, test or replace the starter motor.
