If your engine doesn’t start or is hard to start, it could be due to low or no fuel supply to the high-pressure injection pump. Secondly, make sure that you have clean fuel and good supply pressure. Start by recording and repairing any active DTC as they might be related to the problem.

This amount of pressure can slice into your skin and cause fuel to enter your bloodstream, which could result in death. Do not attempt to find leaks manually as the fuel system contains pressurized fuel up to 25,000 PSI.
In order to diagnose whether your injector pump is failing, you will need a scan tool. Like many long-lasting diesel parts, replacing injectors can be a pretty expensive job.
These injectors fail due to mechanical wear and not dirt, so there’s generally no point in trying to clean them if they show signs of failure. The injectors on the Cummins 5.9 engine should last between 120,000 and 150,000 miles depending on the fuel quality and regular filter maintenance. At some point, the engine may also be hard to start or not start at all. The injector pump can’t handle the loss of pressure forever, which means you will eventually start noticing a lack of power in the engine. However, since the lift pump no longer has enough force to do its job, it will eventually wear down the injector pump. The Cummins 5.9 injection pump will continue drawing fuel out from the lift pump. You might not initially realize that the lift pump is broken. In order to check the performance of fuel system parts, you’ll need a scanner. The fuel is siphoned to the main 5.9 Cummins injection pump, which then sprays it into the engine. One is a lift pump that lifts fuel from the fuel tank. There are two fuel pumps on the 5.9 Cummins. Bad injectors can also cause a knock in the engine. How can you tell when a 5.9 Cummins injector pump replacement is imminent? Some symptoms of 5.9 Cummins injector pump problems include lack of power, not starting, or hard starting.
