I have an 04 5.9 cummins ,put quadzilla adrenaline on it when it gets hot it wigs out and causes engine to do weird stuff. Happened once before i unhooked the adrenaline box let it cool down plug it back in and all was fine . It did it again and now the truck won't start.

Fuel gauge shows empty and tach is buried at 5000 glow plugs don't come on and I can't make it give me a code. Engine will crank but it won't fire....WTF!!!

 

I would check fuses and relays. Also I would leave that quad off for good.

 

Ya those all look good what's the chances of ecm being fried and can it be flashed can it be checked if not on the truck
