Ok so here it goes. Bought my first cummins back in January, 2001 24v totally stock with an edge comp box. It had a bad oil leak so i tried to wash off the crud to help locate the leak ( yeah i know bad idea ) got side tracked and didn't mess with the truck for almost a week. When i did get back to it, it was a no start so i put a code reader on it an got a laundry list of codes. Long story short i came to the conclusion that it was the ecm, so i replaced it. Installed it, truck runs but if you touch to go pedal it dies instantly. Sent it to the shop. Replacd injection pump, lift pump, cam sensor and fixed the tappet cover leak. Still same problem. Sent ecm back thinking it was bad, got it back reinstalled it truck ran fine for 5 minutes and then back to original problem. Anyone have any ideas. I'm stumped ,shop is scratching their heads
