My truck wouldn’t start so i replaced the fuel filter and it ran fine for a week than wouldn’t start again. Took it to a mech, who ran all the computer codes and scans on it and came up with a lift pump pressure problem. Replaced the pump and it ran for 4 days, now it doesn’t start again. any suggestions. They said the injection pump was fine. ---

I don’t know that Dodge engine, but many diesel engines have shutdown valves. Just turning off the fuel pump does not mean the engine is going to stop so they have a special shutdown capability. They can get stuck closed, which means the engine will not start or run until they get the safety off. It could be nothing more than a gunked shutdown valve. Good Luck ---
