    the coil inteminently gets power and ground at different key positions. so im guessing still a bad ign switch or my ecu keeps getting fried.

    I'm sure the ignition switch is part of the problem. That can cause other problems as well. Did you already replace the switch and harness?or replace the switch and repair the harness already?

    And the same problem after you switched the ignition? Then there could be bad wires somewhere. Did You guys test the wires at the mpi relay? There could a short to ground on one of the circuits. Doesn't take much for body parts to cut through insulation. If I have time I'll check my notes for the wires to the mpi relay to see which wires should be power and which should be ground.

    Yea same here, I would maybe try sticking around some 3000gt forums or montero forums, something more common with the v6, and asking for help on there.

    Man, I have two of these and wouldn't trade either for another truck. I know how frustrating things can get sometimes, especially electrical problems, but once you figure it out, you'll be happy you stayed with it. We have a mobile auto electric mechanic in the area who I had to call when I first got mine to track down a short. It took him less than a half an hour and I'd probably still be looking. Any of those in your area? A lot of repair shops call this guy in when they get stumped with electrical issues. Sometimes it's a lot simpler than it appears. Good luck!

    Hay man. I can come up one day and take a look at it for you. But you will need to find a book on it so I can run through the wiring. I might be able to get you pointed in the right direction.

    Man you need to cut all of the harness open and look for the melted wire. Something is melted or broken. I would start where you found the melted stuff the first time and go through it from one end to another. It's in there some where. Don't give up on it now. Just keep the mind set of I always win, and you will...

    haha yeah, the wire was getting signal though i looked at the wrong end of the wire. but i think looking into the harness a good idea, im just scared of wiring. also the fuekl pump doesnt prime when i turn the key on

    more likely the cam sensor being bad, unless it has a crank sensor - never had a v6 so I don't have much to offer here.
