Ok so I have a 1997 k1500 with the 5.7 and I cut the cats out because they were clogged and it started to back fire really bad and then one day it just stopped running and wouldn't fire so I put a new full pump in and still nothing turns out it was an egr fuse that was blown so I put a new one in and it kept blowing the 25s so I put a 30 in and it started right up and ran for a little then shut off again I think because it was to rich because of the o2 sensors so I put resistors on the downstream ones and it ran great was driving it home and it just died and wouldn't restart the fuse isn't blown or anything I'm at the limit of what I can think of and was seeing if anyone else knew thanks
