If you are seeking for a new injection pump for your Dodge Cummins diesel engine, but are not certain which is the best model, than please continue reading. In this article we explain some frequent failures with injection pumps. The Cummins diesel engine manufactured by Dodge amongst 1998 and 2002 came equipped with a Bosch VP44 injection pump. Regrettably these injection pumps have been know to have their fair share of issues and may want to be replaced.

Bosch VP44 injection pumps execute four standard functions:

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

two. Metering the exact amount of fuel for every single injection cycle

3. Varying the timing relative to engine speed.

four. Producing the high fuel pressure needed for injection

The Bosch VP44 is an electronic rotary distributor pump that can differ 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 generally due to a malfunctioning lift pump. Normal fuel pressure is about 15psi and if the pressure drops beneath 5psi an injection pump failure is probable. Don't forget bad lift pumps can run unnoticed until expensive damage is done to the Bosch VP44 injection pump.

The following are the leading two most common mechanical failures:

1. Verify Engine Code 216

This is the most typical mechanical failure and happens 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 exactly where it wears the housing of the pump down until the fuel is able to bypass the piston. Dodge has recognized this dilemma for some time, and they no longer even sell the lift pump that goes on the side of the block anymore, as an alternative they replace it with a unit that is now mounted in the tank.

2. Rotor Seizure

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

Preventing Bosch VP44 injection pump Failure

The best way to steer clear of failures of the Bosch VP44 injection pump is to stop them from occurring. Purchasing a replacement lift pump, one particular that is of a greater high quality than what comes from the factory will aid. If that solution is too pricey, 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 very easily repair the issue prior to you shed the Bosch VP44 injection pump.
