Do a check on the KDP (Killer Dowel Pin) in the websites …Another common symptom of a bad fuel pump is a surging engine. This is caused by too much fuel being sent to the engine. When that happens, you'll notice your engine surging—the vehicle will repeatedly pick up speed and then drop speed, even though you haven't touched the gas pedal or the brake.Cummins ISX Fuel Actuator Problems. Your fuel actuator controls the amount of fuel that enters your injection pump. This means, it also controls the pressure that your pump is able to develop. It also works quite the same way as your throttle valve. As the inlet flow is regulated, you are able to control output volume and pressure.Goldmember. Jun 10, 2021. #29. Cummins has a tsb out for coolant in the fuel and fuel in the coolant. No tsb for coolant into the cylinder as far as I know.
