Starter motors are used to rotate an engine to begin the starting process. A solenoid or motor that has burned out or electrical issues may cause this as well. Without a properly working starter relay and motor, you won’t be able to even back out of a parking space without a jumpstart or tow.

In many cases an intermittent starting problem is linked to a bad wire connection that may become dirty due to exposure under the hood. You'll need to use your megohmmeter to ground test line and load circuits at the starter. A multimeter and a clip-on ammeter are required for troubleshooting. If the overload shows continuity between the two NC terminals, we’ll have to dig in a bit further. When the ignition key is turned a low amperage electrical signal; is sent to the anti-theft system and computer. Hearing clicking without the starter motor moving means the solenoid is transferring the electricity, but it may not be enough.

If you turn the key to the crank position and nothing happens; try jiggling the transmission gear shift lever first. If the fault moved to the other vehicle, then you have a problem with your battery, Charge it or replace it . It’s important to know the Voltage, phases, and Full Load Amperage (FLA) of the motor. Although this kind of problem may arise due to a dead battery as well, you have to check the other symptoms so you can determine which one is at fault. There is a "click" from the solenoid charging, before the click the interior lights dim but once it clicks the lights are back to normal..
