My truck turns over for a second , maybe two and then stops cranking. It will do it over and over. A few days ago my ECM touched a hot battery terminal and that's when it started acting up. Does anyone know if the ECM could be fried? Or could it be something else? My batteries are good, I had them checked and had to replace one of them. But now I'm stumped. I feel like it's probably a bad ECM now!? Any help would be appreciated.
Hey guys my truck is an 06 silverado 6.6 4x. Thx for the responses so far. I think it may have been because i put the truck inside the shop at my work but it did start the night after I first posted this. It died on me a few times but started right back up. It ran for a total of about 30-40 min. The next morning I started it and pulled it forward a little then worked on it with the garage door open and it wouldn't start later that day. Hasn't started since. It's been between 0- 30 degrees around here for a month now. I think I may need to add some additives to the fuel. I also got some codes off of it I can post when I get home later, maybe that will help you guys help me!
