Good morning,

The first thing to check is the battery. Make sure it has 12.6 volts so there is enough power to crank and run the engine.

Next, I would make sure the engine turns. Try and turn the engine manually to be sure it turns.

I attached a wiring diagram for you of the starting system. We need to do some voltage checks for the starter to be sure it is good.

Okay, can you go to the relay and do some testing for me? We need to see if there are any signals to the relay.
