Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi Welcome to Just Answer! Have you replaced anything yet?
ok low rail pressure is caused by either a leak in the high pressure side, a bad lift or injection pump or a blocked fuel filter
ok sounds like you have a bad injection pump from what you are describing.
Unfortunately not much you can do besides replace the injection pump again
The electrical wire going to it is the fuel temp sensor and the fuel return to the tank for when the rail pressure is too high
If you have good pressure into the injection pump but not out the only thing it can be is the pump. The only thing replaceable on the injection pump is the fuel temp sensor The solenoid comes with the pump. The only other thing it could be is a leak after the pump at the rail, one of the delivery tubes or injectors.

Ok thanks for the response.
try clearing them and see which ones come back some of those may be from have stuff unplugged
ok you are getting a fuel fuel related codes but now you also have the one injector code and a glow plug code. That engine is know for wiring harness issue check the engine wiring harness behind the fuel filter where it loops down from the battery and back up to the engine we have seen a lot of broken wire in that area
