Watch the wait to start light,if it lights upon turning the on,does it start?
If it does not light up,turn the key to the start position for just a second and let off,then turn the switch to off. Wait a few seconds then try to start it again.
If this helps crank the truck faster then there is an issue inside either the injection pump or computer. I know this all sounds stupid but I've ran into this more than a few times when replacing the injection pumps after supply pump failure. If you look into the wiring of these trucks you'll see that the supply pump pulls it's voltage striaght from the computer on block mounted pumps,no relays or fuses,100% computer. Pure insanity
Im not saying this "is" the problem just suggesting checking it. Most of us pay no attention to the WTS lights on a cummins
