Unhappy Fuel Supply Problem

I have a 2000 Cummins 5.9L on a 2500 4X4 with chip. The problem is I was accelerating into traffic and the entire engine shut down. No sputtering, no missing, nothing...just quit. I coasted to the side and tried to start it and ther was no turn over. Had 2 friends come look at it.They bled the injectors (4 out of six ...one they couldn't reach) still wouldn't turn over. They tried starting fluid into the turbo. It started but died within 15 seconds. This happened twice. Any clues???

Try the key trick which is "on-off-on-off-on." Don't start the truck just cycle the key 3 times. The odometer should read codes. Second, the fuel sending units can go bad and you may have run out of fuel without knowing. Third, what is your fuel pressure? -- Is your lift pump working? You say you have a chip, did you unplug it and try again?

Last...never put starting fluid in the turbo unless you disconnect the grid heaters. If they cycle on and you have fuel in the manifold it can ignite and be dangerous.

Thanks for info. I did forget to say that when the truck shut down...I mean completely shut down. No radio no gauges, like someone turned off the key.

The ignition trick shows P 1693 which just means there is a problem in another module. The truck has just been filled so I know the tank is at least half full and in bleeding the lines, the sending unit is bringing fuel to the injector pump. I am having someone check the pressure. My question is how would this be connected to loosing the radio at time of shutdown. Upon trying to restart, yes the radio came on.

It could be any number of things. You will want to check ALL your grounds to make sure they are clean and do make ground. Also check all your fuses to make sure none have blown.
When the injector lines were bled, was there abundant fuel coming out of them? If not it could well be your injection pump that has given up the ghost. Finally if the Cam Position Sensor fails or Crank Position Sensor (on older 2nd Gens) you will not start either. Sounds to me like an electrical issue though if you lost all gauges and power to the dash when the engine quit. There is also the remote possibility that the ECM died (pretty unlikely though).
