Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name isCustomerand I an assist you with your question. Are you looking for some possible causes? Do you need a wiring diagram of the starting circuit of your vehicle?
YES, is there is a security light on or flashing when trying to start the engine?
On the dash/instrument cluster
If not, I would suspect a bad starter.
You would have to verify power at the starter just to be sure. You can use a test light or a voltmeter.
The PCM grounds the starter relay. From there, the contacts inside the relay close and send power down to the starter. Here is a wiring diagram.
Good morning! If there is power going to the starter and the starter is not activating, the starter motor is bad and will need to be replaced.
