What causes a fuel injector pump to fail?
The three main causes of fuel injector failure are a burnt-out solenoid, corroded electrical contacts, or leaky seals. If you have the proper equipment and plenty of patience, it is possible to clean and rebuild your own fuel injector. This will save you money over having the part repaired professionally. However, you must be careful.
What should I do if I overload my injector pump?
Apply power briefly to open the valve and clear the injector. However, do not apply power to the injector continuously or you will overload it. Continue to clean the injector with an ultrasonic cleaner if you have one available. Cut off the pintle cap and remove the spacer. Be extremely careful from this point forward.
How do you replace a fuel injector pump?
Touching the pintle at any time can ruin the fuel injector. Remove the fuel filter by poking it out with a sheet metal screw. Tap the new filter into place with a mallet. Heat the new pintle cap to help it slide on. Finally, replace the o-rings and reinstall the fuel injector.
What is the role of the injector pump in a car?
Injector pumps are among the most critical components of a vehicle’s engine. The fuel injector controls the flow of gasoline or diesel into the combustion chamber.
Can a diesel pump be injected into the body?
This is a good reason to take great care when working on diesel systems; escaping fuel at this sort of pressure can easily penetrate skin and clothes, and be injected into body tissues with medical consequences serious enough to warrant amputation.
What’s the pressure of a diesel injection pump?
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.
