If you are hunting for a new injection pump for your Dodge Cummins diesel engine, but are not confident which is the very best model, than please continue reading. In this report we clarify some widespread failures with injection pumps. The Cummins diesel engine manufactured by Dodge in between 1998 and 2002 came equipped with a Bosch VP44 injection pump. However these injection pumps have been know to have their fair share of troubles and could need to have to be replaced.

Bosch VP44 injection pumps perform 4 standard functions:

1. Distributing the high-pressure, metered fuel to every single cylinder at the precise time

2. Metering the exact amount of fuel for each and every injection cycle

three. Varying the timing relative to engine speed.

4. Producing the high fuel pressure needed for injection

The Bosch VP44 is an electronic rotary distributor pump that can vary fuelling and injection timing, and also consists of fuelling, timing, and diagnostic information.

The quantity one cause of Bosch VP44 injection pump failure is a drop in fuel line pressure, which is usually due to a malfunctioning lift pump. Regular fuel pressure is about 15psi and if the pressure drops below 5psi an injection pump failure is probable. Remember negative lift pumps can run unnoticed till pricey damage is completed to the Bosch VP44 injection pump.

The following are the top two most common mechanical failures:

1. Verify Engine Code 216

This is the most common mechanical failure and occurs more than a period of time when weak lift pumps, with low fuel pressure rupture the diaphragm in the front of the injection pump. The timing piston will then vibrate to a point where it wears the housing of the pump down until the fuel is in a position to bypass the piston. Dodge has recognized this problem for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, instead they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

One more mechanical failure with the Bosch VP44 injection pump happens when the rotor seizes in the distributor section of the pump. The most frequent lead to for the seizure is a lack of lubrication. Considering that the fuel lubricates the Bosch VP44 injection pumps, weak lifts pumps can again be blamed for this failure. The seizure will then break the Drive Plate and the truck will quit running, never to begin once again, till the Bosch VP44 injection pump is replaced.

Preventing Bosch VP44 injection pump Failure

The very best way to avoid failures of the Bosch VP44 injection pump is to avoid them from happening. Getting a replacement lift pump, 1 that is of a greater top quality than what comes from the factory will assist. If that solution is as well expensive, you can also install a gauge to monitor your fuel pressure. With the gauge you will be in a position to know when your lift pump is going out and can easily repair the issue ahead of you lose the Bosch VP44 injection pump.
