Wont start

When you say nothing will turn on, does that include all the accessories or just the starter will not turn over?

If the starter will not turn over then we need to check the voltage at the starter. Here is a guide that will help with this:

I included the wiring diagram below which will help with this as well.

However, if nothing works then this could be an ignition switch. If this is the case, then we need to check power from the switch and find out if this is sending voltage to the starter solenoid.

This is also part of the wiring diagram below so let me know what you find with this, and we can go from there.

Thanks.
