A Two-Headed Monster – A Pair of Reasons that Explain Fuel Injector Pump Failure
Problem #1 –Low Fuel Tank Level
If your main goal in life was to destroy diesel fuel pump injectors, you’d run your car with the fuel tank as close to empty as possible. It all has to do with lubrication. With plenty of diesel fuel in the tank, the fuel pump bearings receive plenty of lubrication. With a near-empty tank, the fuel system is suddenly pushing air instead of diesel fuel. Anything but diesel fuel can wear out the fuel pump bearings, which means the fuel injectors will not receive the fuel at the pressurized level (30,000 psi, 40,000 psi, etc.) it should be.
Problem #2 – Foreign Object Inside Injector
Diesel fuel pump injectors are high-precision components. They also deal with a tremendous amount of motion and other stresses. One small visitor inside (a piece of dust, debris, etc.) can clog the injector. Worse yet, a microscopic object can leave the injector open all the time. If the injector can’t close, cylinder performance is compromised.
Problem #3 – Bad Injector Timing
Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
Here’s the good news about fuel injector pump problems: avoiding disaster is simple. In fact, if you do these three things, you’ll enjoy great performance and minimal repair costs:
· Purchase clean, reliable fuel
· Change your fuel filter every 40,000 miles
· Keep your fuel tank at least one-quarter full most of the time
Injection pump – this part is a meter and pressurize fuel for injection. Governor – supply fuel in accordance to the load. Fuel injector – supplies fuel from the injection pump to the cylinders. Fuel filter – to filter dirt, duct and abrasive particles from blocking the injection system.
