I have an 06 5.9 no mods, strarted running rough while pulling 20,000 lbs, then lost power. Changed fuel filter and fcr, gained power but still running rough then it died. Now starts then dies. If you unplug the fuel sensor or regulator
it'll stay running just runs rough.

 

Fuel sensor or regulator? Where did you find this plug to unplug it? Starts easy or got to crank a lot? How long will it run? And you mean rough but not firing on all cyclinders or? Any fuel smell or extra oil level on the dipstick?

 

I can unplug the sensor on the fuel rail or the actuator on the back of the cp3. Truck starts right up. Puffs small amount of white smoke and light fuel smell from exhaust. Runs rough like one cyl not firing.

Not making any oil. Runs as long as i leave the sensor or actuator unplugged. If I start without unplugging it dies in 1 to 2 sec after firing.

 

Bad injector start pulling them out! Keeps running because you max out the pressure when you unplug the FCA .

 

Will the fuel sensor default it too.

 

Not sure on that I think so but you can call Todd at T&C Diesel google him! Top notch fuel guy!

 

Will do thanks!
