Power Driven Diesel VP44 Fuel Injection Pump for 98-02 Cummins – Bundle

The VP44 injection pump for the 1998-2002 Cummins is the most common pump found on Dodge diesel trucks.

This pump is built with a Brand new Bosch Computer.

These VP44 pumps are rebuilt by a certified Bosch shop and have all Bosch upgrades and updates including new electronics and steel housing.

These pumps include a 1 Year/ Unlimited mile warranty.* The VP44 is the most advanced pump Bosch has made.

It uses the computer or PSG to control both fueling and timing. It is also more sensitive and dependent on the lift pump for cooling and lubrication.

If the lift pump fails or is unable to keep 5psi (recommended is 13psi) of fuel pressure your pump is susceptible to damage, overheating and failure.

CORE:

Core deposit of $500 required unless core sent in advance. If a rebuildable core (ie. not seized, damaged, contaminated, disassembled) is not received in 30 days from date of shipment a reduced core credit of $200 applies for late cores.

IF YOU PURCHASE AN SO 235HP PUMP, YOU MUST RETURN AN SO 235HP PUMP.

ANYTHING OTHER THAN AN SO 235HP PUMP RETURNED WILL RESULT IN 1/2 CREDIT.

VP44 DISCLAIMERS:

Failure to replace feed pump along with the Injection Pump may result in damage not covered under warranty.

It is highly recommended that the feed pump be changed along with the injection pump.

The VP44 pump uses fuel to cool and lubricate the pump.

The tolerances between the head and the rotor are very tight.

Performance chips affect the cooling rate of the pump.

The pump will become hotter due to excessive RPMs from the chips programming. When the throttle is backed off the fuel to the pump is reduced, and the pumps cooling capabilities are greatly reduced.

Since the pump is hotter from the increased RPMs the rotor seizes in the head and the pump fails.

An alternative to cutting/tapping into the pump wires is to use a larger set of injectors or/and a chip that plugs directly into the trucks ECM.

This approach will allow for an increase in HP while not excessively heating the fuel pump.

TROUBLESHOOTING:

Often if your VP44 failed, the root cause is a bad or failing lift pump.

The stock lift pump does not supply sufficient pressure for stock power.

It is mounted to the engine block and has to push through some small fittings and lines that act as a restriction, even worse the pump has to pull fuel all the way from the tank.

Electric pumps are designed to PUSH not PULL fuel.

The in tank pump recommended by Dodge dealers is not much better.

It may flow a slightly higher volume but at pressures even lower than the stock pump.

It is placed inside the fuel tank to keep it cool and reduce failures, but when it fails you are out another $500 for the dealer to drop your tank and replace the pump again.

DEFECTIVE VP44 CODES:

The retrieval of codes does not constitute an engine diagnosis.

However, there are some codes that usually indicate a defective injection pump.

A current P1688 always means that the pump is bad, there is no further diagnosis required.

Code P0216 is probably the most common code for VP44 Pumps.

If transfer pump pressure has been checked and is O.K., the injection pump is defective.

It is rare to get a P0216 for contamination but it may be worth trying some quality diesel fuel cleaner/conditioner with the small percentage that it may clean the internals of the pump to remove varnish and allow the pump to time fuel delivery correctly.

Other codes that are less common are P0180, P0181, P0215, P0251, P0252, P0253, P0254, P0370, P1287, P1689 and P1690.

These codes USUALLY, but not always indicate a defective pump.

There are wiring and power checks to be performed if these codes are present.

These codes relate to Dodge pickups only, and are not for any other ISB application.
