My truck just died one day and will not start. If you spay starting fluid it will start. The pump does not kick on with the key so I took it out and tested it directly to a battery it runs fine. So I continued to look for electrical issues. The cut off switch on the passenger side is not tripped all fuses are fine I just am getting no power to the plug under the truck. It is a 4.2 v-6.
Do you
have the same problem?

Have not check the terminalls will try that. I dont have power at the shut off switch. The way I tested it was 1. Ran a jumper on the switch with no luck 2. Used a testing light and tried it in all 3 wires with no power?
