2000 gmc 3500 cargo wont start
I've checked and cleaned all the grounds I can find. Batteries are good. Starter is almost new. When i bench test it it works fine. When i turn the key to start it just clicks. 1 in 20 or so attempts to start and it will turn over. When it does turn over it melted the negative off the second battery. Re checked grounds cable batteries. Replaced neg clamp and now its starting to melt positive clamp? Any ideas would be welcome

couple things to check aside from grounds and neutral safety. First check o see if you have fuel at the test **** to the right of your injection pump. If you do make sure your system isn't air bound. If that doesn't work, then it could be the PMD on the side of the injection pump. It could even be the injection pump but that can be eliminated by cranking the motor with a injector nut loosened to see if you have fuel at the injector. Sorry but these 6.5's are a pain to diagnose, I had to find out all these the hard way. Good luck
