Help no start problem 99 24v
 

I was driveing my 3500 yesterday it shut off like you turn the key off I checked the lift pump 12 pds pressure filter full changed filter still no start no fuel to injectors I did the code test with the trip button & it said No bus & now my A/C clucht just clicks on & off all the time the key is on now need help fast am walking :confused:

Most likely a VP$$. If you have fuel exiting the filter canister, but no fuel at the injectors there is only one thing it could be! VP$$.

It's actually VP44 if you're not familiar, but if you look at your keyboard and hold shift it is VP$$!!!

If you feel like spending the money go for a Blue Chip VP. $1600 and better electronics to handle the heat compared to the $1500 reman that a Cummins Shop or Dealer will hit you for. Or if you are content with just a normal reman it'll range from $800 up to $1500 depending on where you find it.

I wish I had better news for you. :(

Not sure thinking more engine control puter it will not come out of test mode now even disconnected batterys for an hour with key on still in diag mode fuse box buzzing with A/C clutch clickinb on & off
