Im sure many people may know more about this then i do, but i have P0148 popping up on my Diagnostic tool. i know it could be a lift pump, FCA, relief valve, cracked injector, or plugged filter, or ect. what you yall suggest checking first? any help would be greatly appreciated.

if my sig aint filled out i have a 2004 dodge 2500 4x4, its all stock and i have 199000 miles on it, the motor has had a new cam shaft put in in 3500 miles ago. havent put any gauges on it due to me spending money on getting my motor fixed and my tranny rebuilt.

 

i just dealt with this on Friday what i did is re torque my crossover tubes to the injectors it took me 3hrs taking my time i would start there it is free and is the first place to check after that you get to spend money
and i put them to 44# like other have done the book calls for 37# there is a updated spec to do them to 41# so do as you think is best in that aspect

and as you just had your truck apart i would do that anyways i just got 3000 miles on a new motor and that fixed me up

 

i shall give that a try, thanks.

 

Before torquing anything, check the connector plug at the rail pressure sensor. I had a plug in chip that connected there, and the harness that was supplied with the chip was not up to par. It caused that code and another one. Some di-electric grease in that connector and making sure it was plugged in good solved the issue.

 

Okay, i shall check that also. Thanks nickbeek.
