Diesel Injection Pump Replacement

What is a diesel injection pump?

The diesel injection pump produces the high fuel pressure required by diesel fuel injectors. Its shaft rotates in time with the engine, allowing it to send a high pressure fuel pulse to each injector at the proper time.

How does the diesel injection pump work?

The diesel injection pump, also called high pressure fuel pump (HPFP), is driven, on most vehicles, by the timing chain, timing belt, or timing gear. It receives slightly pressurized fuel from the fuel tank in a large volume, and attempts to compress the liquid, resulting in a moderate flow at an extremely high pressure. In fact, the fuel line pressure this pump creates can reach 27,000 PSI at high engine speeds. This high pressure is needed to provide diesel to the engine as fast as fuel is needed.

Failure of the diesel injection pump can cause hard starting, cylinder misfiring, or a lack of power.

What are the symptoms related to a bad diesel injection pump?

How does the diesel injection pump work?

Failure of the diesel injection pump can cause hard starting, cylinder misfiring, or a lack of power.

What are the symptoms related to a bad diesel injection pump?

Hard starting, no starting or stalling immediately after starting are common symptoms of a failed or failing diesel injection pump. When the vehicle does start, misfires, loss of power and illumination of the check engine light for OBD codes relating to exhaust and emissions, fuel delivery, and misfires will be present. Also, getting the engine to speed up may be sluggish, and the engine may randomly surge with power.

Can I drive with a diesel injection pump problem?

After the fuel injection pump fails, the fuel distributor and injectors will not have sufficient power to drive the vehicle without severe driveability issues. Also, continuing to drive with a failed high pressure fuel pump could lead to metal shavings being passed through the fuel system as the fuel pump continues to spin. Since modern diesel fuel systems have return fuel lines, the metal shavings can make their way through the high pressure fuel pump, through the fuel distributor, to the injectors, and through the return line to the fuel tank, and back into the new LPFP, once replaced. To help avoid this costly repair, the vehicle should be towed to a repair facility.

How often do diesel injection pumps need to be replaced?

High pressure fuel pumps on diesel engines have incredibly long service lives. They tend to last between 100,000 and 150,000 miles, and repeat replacements are not typical. A small handful of European commuter cars recommend replacement as scheduled maintenance, but this is a very small number. It is important that the fuel pump be periodically inspected for leaks, wear, shaft play, and metal shavings, as failure of the injection pump can send these metal shavings through the entire fuel system.

How are diesel injection pump issues diagnosed?

When the injection pump fails, diagnostics will lead the technician to the fuel system quickly. Not only will the technician find a sizeable drop in fuel rail pressure, but the fuel system may be completely full of metal shavings. When these shavings are spotted, the technician will likely remove and inspect the high pressure fuel pump, where the metal shavings originated. The technician will go about examining and removing fuel system components subjected to these shavings, replacing those components which must operate at extreme pressures, and salvaging low pressure items where possible.

The injector pump may be replaced when the problem is actually dirty fuel filter(s), low engine compression, worn out glow plugs, failed fuel supply pump, defective glow plug relay, improper injector pump timing, and/or poor fuel quality.

How is a diesel injection pump replaced?

Replacing the injection pump normally involves removal of an engine mount, for transverse or small-engine diesels, removal of all accessory components, the timing cover, timing components, high and low pressure fuel lines, and finally, the pump and associated electrical connectors may be removed. Reassembly is the reverse of removal, and if the pump failed, the system will be thoroughly inspected before allowing the vehicle to restart. Full step-by-step procedures for the two common types of diesel injection pumps can be found below: Gear Driven Injection Pump

Disconnect the negative battery terminal
Remove any components that obstruct access to the injection pump
Disconnect all fuel lines and electrical connectors to the injector pump
Remove the injector drive gear cover, if equipped
Lock the injector drive gear in place with the locking pin
Remove the fasteners that secure the injector pump
Remove the old injector pump and clean the mounting area
Install the new injector pump and "time it" with the drive gear
Secure the new injector pump with its fasteners
Reconnect all electrical connectors and fuel lines
Install any other removed components
Reconnect the negative battery terminal and clear any codes
Start the engine and verify the injector timing with the proper tool
Perform a comprehensive test drive to verify the repair

Timing Belt Driven Injection Pump

Disconnect the negative battery terminal
Remove any drive belts that block access to the injection pump
Disconnect any fuel lines and electrical connectors
Remove the timing belt cover(s) and, by hand, rotate the engine to the timing marks
Loosen the timing belt and pull it back from the injection pump
Remove the injection pump fasteners and the injection pump
Clean the mounting area and install the new injection pump
Secure the injection pump fasteners and re-attach the timing belt
Verify that the alignment of the timing marks are still correct
Install the timing cover, drive belts, fuel lines, and electrical connectors
Reconnect the negative battery terminal and clear any codes
Perform a comprehensive test drive to verify the repair

The injection pump may fail if the fuel supply pump doesn't deliver the proper amount of fuel to the injection pump. Therefore, it's very important that the supply pump is checked and replaced if necessary.
