    It's not turning over at all, it's not even clicking. I hear the relay but nothing from the starter.

    I'm about to go down to the garage and put the test light on it and see if I'm getting power, is there any fuses/relays I should check?

      at first i would check the main relay on your harness, the white one. and see if that has gone bad. Sometimes they just go out for no reason.

      another possibility, one that happened to me actually, is i went to start it and it did the same thing as yours. I checked wiring, relays, etc... and then i was grasping at straws thinking my starter was just stuck. Soo... i grabbed a long piece of 1"x1" piece of wood about 3ft long and set it against the starter and gave it a few hard taps with a hammer.

      fired right up after that. i guess sometimes that starters can just get stuck for various reasons. check those two things and if those dont work, we'll go from there.

          I'll check the white relay on the harness tomorrow after work. Good news is I got it to start. I ran a wire to the + terminal under the hood to a push start button and from the button to the solenoid and now it starts when I push the button.

          But I'll make sure to check that relay, so I can put it back they way it was.
