99 7.4l blows ECM1 fuse at random
I inherited this truck from my father, Ive had a couple other suburbans before but none with the 7.4l. this one has a western plow and runs great (for the most part) until it randomly blows the ECM1 fuse under the hood. After it blows, I would replace it and the truck would start right back up...- Cnelson420
