No power to starter
Here's what happens in the start sequence when ypi turn the key.
When you turn the key, you should at least hear the starter solenoid click. When you turn the key the ignition switch sends 12 volts to the Starter solenoid ( really just a relay). The Solenoid closes and applies 12 volts (at a high current) to the starter motor to crank the engine. If you have a way to measure voltage, you should get 12 volts at the small terminal on the starter solenoid. The solenoid is mounted on the top of the starter motor.If you get
no voltage, probably an ignition switch If you get 12 volts and the starter doesn't crank the starter is probably defective. At this [point take a small hammer and tap the starter motor, not hard, just medium. Sometimes this will cause the starter motor to catch next time you turn the key. Best bet is to remove the starter motor (with solenoid attached) and take it to an Auto Zone type store where they can check it out for you. Be sure you disconnect the ground terminal of the battery before you attempt to remove the starter motor.
