    The Posi-Lok is a bit expensive (about $200 from what I have seen) but would definitely be worth it. The actuator is run off of internal gas which expands when hot and pushes outward, locking the...

    I replaced the fuel pump relay in my Sub early September of last year. It was an easy replacement and cheap too (about $20). I have not had a starting issue since. Good luck with this.

    Royal Purple's Purple Ice

    So, it is starting to heat up here in the high desert, and so is my truck. It's a '91 V1500 Sub with the 5.7 and sadly a 2 core radiator. Also, not to mention 310k on the original drivetrain.

    If you can't find the problem, you should check into a Posi-Lok kit. They are about $200 or so, and eliminate the thermal actuator. It's a push/pull system that allows you to lock the front end...

    I'm not sure how your brake system is set up, but with mine, I was able to use a large flat punch and a hammer to bend the two clips on the outside against the caliper more. A couple of good whacks...

    I am not quite sure about a '94, but the '95 fuse box is on the driver's side of the dash, right next to the door. There should be a legend to tell you which fuse is which.

    Good luck!

    I have been considering an aluminum 3 core for my '91. The best deals I have seen are on Ebay. They range from $150-$250, and are supposed to be direct fit.

    Just find an existing grommet that you can thread it through. That's what I had to do on my '91 Sub. Not very difficult to do.
