Sometimes it will and will start. I have not had any problems or symptoms that something was going wrong.

When it does not start, in the junction box on passenger side, firewall compartment, from the passenger side, there is the fuel pump relay, then the two bolts next in line from the fuel pump relay heat up to the point of smoking.

Anyone know what the wires attached to the two bolt positions next to the fuel pump relay in this junction box go to or come from ?

I have checked the battery, I think I have a short somewhere but could it be a starter issue or ignition switch issue or ?


Any ideas or help would be appreciated.

You have a bad ground in your start circuit. Check the connection for the ground cable at the battery, frame , engine, and chassis. It will be one or all of these.
