I've replaced the run/start relay. Tried jump starter with a screwdriver and it just clicks. Any suggestions?

If you jump the starter at the starter and it just clicks, you either have a bad starter or a locked up engine. Have you tried turning it over by hand? Also, these vehicles have issues with loose pin fit at the relay box.

Thank goodness no locked up motor. Checked pins at junction box all okay. Charging battery now to see if it's the starter.

Good evening,

I attached a wiring diagram of the starting system for you to view.

You will need to test for voltage to the starter solenoid with the key in the park position. If you have no power, then we need to do testing at the relay.

I would also load test the battery and make sure you have 12.6 volts.
