- Get two wires long enough to reach from the battery to the VP44 injection pump.
- Install an INSULATED ¼ inch female spade connector onto one end of each wire.
- Use a set of dykes and cut the flat part and one of the "curls" away from each spade connector to leave one "curl," which will be about the right ...

Can a VP44 be rebuilt?
We offer many versions of rebuilt VP44 injection pumps to satisfy everyone's needs and pocketbook.
What happens when a VP44 fails?
The most common mechanical failure of the VP44 pump is rupturing of the diaphragm in the front of the injection pump. The diaphragm ruptures allowing the timing piston to vibrate and damage the front cover until fuel bypasses. This will cause the dreaded check engine trouble code P0216.

How long do VP44 pumps last?
Despite the favorable attributes, the 5.9L Cummins in this generation uses a VP44 injection pump (the weak link, if you will) known for lasting anywhere between 100,000 to 150,000 miles before it fails completely or throws OBD-II "death codes" at the owner for quite some time (P0216 is a popular one) before conking out ...

Is VP44 mechanical?
Now for the fun part, the VP44. It is a rotary style medium high pressure injection pump that is mostly mechanical with two electronically controlled components in it.
How much fuel pressure does a VP44 need?
approx. 12 PSIThe VP44 is a very sensitive pump and needs approx. 12 PSI to run properly.
Is a VP44 timed?
VP44 Timing Principles Timing in the VP44 is controlled by an internal timing piston coupled to a cam ring inside the pump. The timing piston is moved by fuel pressure. The amount of fuel pressure in the timing piston assembly housing is controlled by an internal transfer pump and a pulsating timing solenoid valve.
How does a VP44 injection pump work?
What is the VP44 and how does it work? The VP44 fuel pump is an electronically controlled rotary fuel injection pump; the pump controls the injection quantity & timing of the fuel injection. Engines that use these pumps also use mechanical injectors which control injection pressure (400bar approx. nominal pressure).
How do you keep a VP44 alive?
Nine times out of 10, having trouble restarting a warm engine means the VP44 is on its way out. The only way to ensure the VP44 stays as cool as possible is to feed it good supply pressure and volume.

What is the fuel rail pressure on a 5.9 Cummins?
approximately 25,000 PSAThe Dodge Ram 5.9L Common Rail Cummins diesel engine contains a relief valve in the fuel rail, This fuel pump relief valve is designed to relieve the fuel rail pressure at approximately 25,000 PSA. The common rail uses the relief valve to avoid damage to the fuel injectors.
How does a VP44 injection pump work?
What is the VP44 and how does it work? The VP44 fuel pump is an electronically controlled rotary fuel injection pump; the pump controls the injection quantity & timing of the fuel injection. Engines that use these pumps also use mechanical injectors which control injection pressure (400bar approx. nominal pressure).
What is a VP44 pump?
What is a VP44? A VP44 electronic rotary distribution pump that distributes and meters high pressure fuel required for injection. It is found on the 1998.5-2002 dodge Ram 2500 and 3500 light duty trucks. The VP44 pump can also be found on several mid-range and agricultural engines.
Why is my VP44 216 code?
This can be caused by low lift pump pressure or a worn out housing on the injection pump.
Why does my injection pump fail?
This component fails due to "Lead Free" solder that secures the components to the circuit board. The use of this kind of solder is mandated by the Federal Government's EPA division. Heat and heat cycles make the solder crystalline over time and create an intermittent electrical connection, which makes the pump do all kinds of naughty things.
What happens when a Bosch rotor seizes?
What actually happens when the rotor seizes, and this is from a Bosch Factory Rep, the slot in the rotor interferes with the distributor because of an inferior deburring process. In layman’s terms “deburring” is eliminating sharp edges. As a sharp edge isn’t strong, it deflects under the 4600-PSI inside the pump. The sharp edge deflects and interferes with the distributor and galls both mating parts and then seizes. The drive plate then breaks and only the input shaft of the pump rotates, so no high pressure fuel is delivered to the injectors.
What is a problem with a 2000 truck pump?
A common problem with original pumps in 1998 through 2000 trucks, is the rotor seizes in the distributor section of the pump. This is also common in rebuilt pumps that don't have the upgraded rotor, distributor and coating.
Is Bosch pump good?
There have been a bunch of mechanical and electronic upgrades for these pumps made available from Bosch, and they have proven to be much better than those used when this pump was originally made. The mechanical upgrades have all been a winner in my experience. They seem to last a long time and are surely worth using in a rebuild scenario, but they cost money so when the typical rebuilder is trying to save money in a typical rebuild, they just aren't used.
