So I have had a 99 Cummins for some time now and it came with a raptor fuel pump and edge programmer. It also had a switch in the cab to turn the fuel pump on. When I first got the truck the WTS light was delayed but turned on and after a few starts it started coming on like normal and I had the fuel switched from the switch to my ignition so it came on without having to flip a switch but after I went a vacation and accidentally left the key in the auxiliary position and ran the batteries dead there has been no WTS light. When we would try to jump it the light came on but after the last one it won't. Tried unplugging batteries and letting it sit then putting the cables back on and the light would work for a min but would quit again. The edge would read about codes for the companion moduel and the fuel pump relay and for voltage high on TPS and it had a code for glow plug circuit but Cummins have grid heaters. The truck would still start but it would most of the time would either need a few more cranks or would fire right up. I took it to a shop and they said it was the computer on my firewall so I sent it off to get it reprogrammed and they called saying it was fine and now I have no idea and need help ASAP please help!
