we have a 2005 Duramax 6.6 GMC crew cab that has ran perfectly fine when we bought it from the dealer, my mom loves the truck (mainly because it rolls coal) and recently she was driving down the main Street in town and the truck shut down, she was not able to get it to turn over at all (guages just drop down to zero) we've jumped the starter and we know the starter is good, is has a chip in it for rolling coal and towing ect... before the failure we had to install a new water pump because it leaked like crazy, i have no idea what could be wrong with it. (i'm more of a carburetor guy myself) please help!!!!
