Suggestion 4: Remove the key from the ignition switch. This will prevent the engine from starting... in case the starter motor is OK. Suggestion 5: If you're vehicle has a standard transmission... make sure that it's out of gear and in neutral, and the parking brake is activated/on.ASE 2: The starter motor DID NOT crank the engine. This usually means that your starter motor is BAD and needs to be rebuilt or replaced. I suggest one more test and this is to test the battery cable (that attaches to the starter motor starter motor) for corrosion.
