02 Cummins acts like it is not geting fuel when pedal is pressed
I did a 5 min search but didnt find anyone with the exact same problems so decided to ask, my 5.9l 2002 dodge ram 2500 cummins with a 47re is trowing codes I keep clearing them and as soon as I start the truck they come back. My codes are p0121 p0122 p0222 p0236, I've looked them up but I dont know what I'm looking at 
. someone smarter than me please help, I put a new timbo apps in with in the past month to get rid of the p0122 code I was getting. It stopped for a month and ran fine than started doing this, I also have a new fuel filter I put in at the same time. It feels like the truck is not getting any fuel as soon as I press the pedal, but idles fine, I'm hoping its not the vp44 thanks for any help you can give.

Are there any modifications done to the truck and engine? Please list any that are done.

P0236 is an over boost code, the rest are all related to the APPS. When the new APPS was installed was it rester?

You can try a reset, no promises though.
-Disconnect batteries for a 1/2 hour, then reconnect.
-Turn key to run, but DON NOT start
_Depress pedal all the way to the floor, and then bring back up. Do both motions taking about 3 seconds to complete the travel each way
-Key to off, then run as normal.
This teaches, or relearns the the position and travel of the APPS into the computer.

Care to explain that one a bit more?
