Regeneration of injection pumps and injectors - how much does it cost and is it effective? How much does a fuel pump repair cost? Repair of injection pump and fuel system

When a car has fuel delivery problems, its component will not work properly. Therefore, the repair of the Common Rail BOSCH, delphi or denso injection pump is crucial in the event of problems with them. If you notice alarming symptoms, it is best to contact a mechanic quickly. You can save money, because replacing the entire device is much more expensive than regenerating it. When is an injection pump diagnosis really useful? Check out the estimated prices and find out how it all looks in practice. Read!

How does an injection pump work? Engine components

This device has been used in diesel engines since 1927. It consists of several main elements. The first is the clamping element, which consists of a pestle and a cylinder. They should fit perfectly with each other. In addition, the pump also includes:

• outlet valve;
• connector;
• connecting bolt;
• collar;
• protector;
• lock-nut;
• adjustment plate. 

However, it is the first element that is the most important. The fuel flows to the piston which moves up and shuts off the fuel supply when needed. When the pressure in the cabin increases, it opens the valve and enters the cylinder. 

Restoration of injection pump. When does it get bad?

The main cause of failure, causing the need for regeneration of the injection pump, is, of course, excessive operation of the device. The pump wears out like any other vehicle component and fails from time to time. However, its service life can be significantly reduced due to low-quality fuel, which negatively affects the entire technical system of the car. Other malfunctions in the fuel system components can also cause the problem. It should be borne in mind that the injection pump in diesel engines is a rather complex device, so many of its fragments can break and wear out during everyday operation.

What is injection pump regeneration?

Fuel pump repairs can look different, and it's important what went wrong. However, the beginning is almost always the same. The first step is to disassemble the pump. The second step is a thorough wash. In professional factories, this is done with an ultrasonic cleaner. 

Only then can the status of the device be checked more accurately. Then you can proceed to disassemble the pump, and then replace the damaged elements. Therefore, the process takes a long time. Sometimes it makes sense to buy a pump that has undergone less complex repairs.

Professional service for the restoration of injection pump - price

How much it costs to repair and regenerate an injection pump depends on many factors. Not only the model of the car will be important (the prices for spare parts depend on this), but also which part is broken and how difficult it is to fix it. For this reason, it is difficult to specify the amount you will have to pay. This will likely be individually determined by your bodyshop. However, you will probably have to take into account the cost between 1000 and 200 euros. Regenerating nozzles is cheaper than replacing a pump with a new one, because it can even cost more than 200 euros.

Regeneration of injection pumps for agricultural tractors

High pressure fuel pumps are present not only in passenger cars, but also in agricultural tractors. Therefore, if you are a farmer, also pay attention to the symptoms that may indicate the gradual degradation of this element. If it breaks, contact a tractor repair shop. While they are similar in design to passenger cars, professionals who only deal with passenger cars may not have the tough enough equipment to take care of your tractor. Make sure the mechanic is using new components during repairs. Only then will the regeneration of the injection pump and injectors bring the expected results and restore the performance of this part of the engine.

Regeneration of injection pump. Symptoms of failures and malfunctions in the fuel system

If your high pressure pump is broken, you will probably quickly notice that something is wrong with it. First, you will have trouble starting the car. If you can't start the engine at all, the problem could be a damaged pump shaft. A cold start problem often has the same cause. A sign of problems with the pump is also a loss of power from the motor and its swaying during operation. Smoke and louder-than-usual engine running should also be a concern. If you notice any of these problems, contact your mechanic immediately.

Regeneration of injectors is laborious and requires preparatory work, but it will cost much less than a complete replacement. If the damage to the pump in your car or tractor is minor, then this should be the best solution.
