Should a flaw occur in the starting circuit, do not unreasonably conclude that the starter is responsible for it. Start by checking to ensure
Battery Cable clamps are clean and tight. Additionally, check the state of the battery cables and replace any bad ones. Test the battery to see if all tests are passed, and then replace if required. Check wiring and connections of
Starter Solenoid as well as tightness of starter mounting bolts. Check for battery voltage at the solenoid if the starter does not activate when the ignition switch is turned to start position, back probe the S terminal on the solenoid while turning ignition switch to start position. In case voltage is not accessible look in fuse box engine compartment fuse links and fuses or passenger compartment fuse panel for blown fusible links and fuses. If transaxle range sensor operation is impaired or shifter lever not in PARK or NEUTRAL, check transmission inhibit relay circuitry. For vehicles equipped with an antitheft alarm, look at circuit and control module for any shorted circuits or damaged components. If there is a voltage supply but no motor rotation from the starter motor, remove it from engine and test on bench. On bench remove starter/solenoid assembly if starter has been provided with voltage but does not turn over. The starter/solenoid assembly is working properly if plunger of solenoid extends through pinion drive system.
