LB7 CRANKS BUT NO START

[Bradgrantham59]

No the truck actually caught fire during welding by a friend so now I have a 2006 lbz LOL

Well that's one way to "fix" a crank-no start problem permanently. Bummer about the fire but glad you're OK.

LOL true big plans for the lbz in the near future plus it’s a nice upgrade

I have the exact same problem on a customer's truck. I did all the same stuff and it still won't fire. No power to the injectors. I am at a loss. Unfortunately, this one didn't go up in flames!

LOL from my understanding gm themselves have to match the electronics to each other if all grounds are good and no rubbed they worrs are found

Arson is a crime. Just sayin'....

I don't have any rubbed wires. I have looked at everything. I am starting to think it is a canbus issue. I am going to get this come hell or high water
