Ok guys there is a guy at work with a 2006 5.9 CR and his truck threw a code P0260 and he says when this happens the truck has no power. He tells me sometimes after he shuts the truck down for a little while and then fires it back up it then all is good? Any help is much appreciated.

P0260 Injection Pump Fuel Metering Control "B" Intermittent Injector Let me do some research for ya and I'll post up more information. The code above is a generic definition so let me dig in the morning on this and I'll post more...

What Mike said the code is, probably means/sounds like it's the FCA or Fuel Control Actuator. It's on the backside of the CP3, has a plug that runs to it, and it responsible for "metering" the amount of fuel that goes into the CP3/injection pump. The plug sends varying voltages to it from the trucks computer based on input from the various sensors on the truck.

Well after looking through my books here I can't find a P0260 code for a 2006 Dodge Cummins at all... But looking at the generic code reference I would say its a fuel system related fault and Dorkweed might have a good idea there...:smart:

It's a weatherproof locking type connector, so I would doubt that loose and wet could be the cause. However, the FCA's do go out from time to time. Your symptoms are classic for a FCA that is sticking or worn out or just failing. To test the FCA, unplug the plug that goes to it on the back of the CP3 and start the truck. Or unplug it while the truck is running. This'll max out rail pressure (25-26,000psi if you have a gauge) even at idle and you should have terrible injector knock. That should eliminate electical problem.

Excuse this question it might be dumb but what is a FCA?
