Truck Meysteriously shut down and wont restart
Here is my truck: 03 3500 4x4 dually with an II Double Dragon CP3 , 200 hp injectors , Phat Shaft 71 turbo / Dr. performance pressure module / PPE Programmer / FASS 150/150 / New fully built engine installed in February this year. The CP3 and injectors were also new then. It has about 5000 miles on it since the new set up.
So this is a new one for me. Been driving my truck without any kind of problems all day. Had my truck idling for about 45 minutes without any kind of problems. Went to leave my shop , used a little bit of throttle going in reverse , when I put my truck in drive and eased into the throttle I got up to 30 mph. Then the truck made what sounded like a fuel pressure spike then the rail pressure gauge went nuts and it shut down. It isnt leaking any fuel (20 psi of fuel pressure) , it isnt making any rail pressure , no smoke from the stacks or oil filler cap , nothing in my oil or coolant , no broken or leaking fuel lines. Has a little bit of a funny sound when it turns over but it turns over smooth. It isnt throwing any kind of codes either. Im just stumped and any ideas would be greatly appreciated.

not much into cr either...i would say check the relays and fuses. dont know if there is something that would be stopping pressure to the rail?

What about the rail press sensor or press relief valve? Are you getting and fuel at the rail while rolling it over?

sounds like your FCA on the back of the injection pump stuck...mine stuck once but it would still run but the rail pressure was like it was at half throttle all the time

Hey thank all of you for the replies. I dont have a pressure relief valve, I have a dual feed line. Already had tested the FCA , I keep extras at my shop for customers. I meant to post this the next morning and got busy and forgot.
Well got to mess with it a bit this morning and I unhooked the feed line to the rail to see if the CP3 was even pumping fuel and it was , but then while cranking on it I had a freeze plug blow out of the pump. Guess its time to pull a pump and send it off. And injectors too while im at it.
