I have a 96 cummins. It's never done this to me before it just happened now. I was going to change the grid heater relays because the one is broke and don't work. But I ended up leaving it alone now how ever the problem here is the truck will turn over and run as long as I have the key turned over with the starter engaged. Its never done it to me before as well as my rpm gauge isn't moving when it's on either. Please help me here As I have no idea why it's doing this but really need to get it resolved!
Thanks!!
Thanks!!
