I did the entire full pump because it wasn't turning on and after that I tried to start it and it still wouldn't start so I looked at the fuses and I think it is called the egr fuse sound I put a new one in and it started and idled fine put it in drive and it kept blowing so I went up to a 30...
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...
