Fuel Rail Pressure Low During Idle or Decel Fuel Cut-Off (DFCO)

Anyone know what would cause this trouble code? I have had water in fuel and trying to get it out. Would this bring up this code?? Thanks for any info.:)

Sounds like a FPRV problem.

What is that? I am not too savvy on diesels. I know I love my truck tho:)

What PoPsRacing said.... I was getting 1094's for a while until I installed the PPE race valve.

The FPRV is the relief valve on the back of the drivers side fuel rail, under the Glow Plug Control Module. They often get "weak", causing them to trip 1093's and other rail pressure related codes prematurely. Depending how much you've gotten similar codes (1093/1094), you may be able to get away with shimming the FPRV, or you might need a new one.

So where do you get a PPE race valve and how much are they? I have been getting really rough idling, now it started running rough even when I am putting my foot in it. I thought that it may be my harness connectors, so I icepicked them. I pushed too damn hard and ruined the connector. Now I am waiting for new connectors to show up. I have the wires hooked to the fuel injector now without the connector housing. It sure runs bad.:(

Go to ppediesel.com and go under performance shop, then fuel/intake etc. There it is. 50 bucks. Just give them a call.
