If you drive a newer diesel engine, you have a fuel pump that transports the fuel from the tank to the fuel injectors. The average lifespan of a fuel pump is about 100,000 miles. Therefore, if you drive a high-mileage diesel engine, it’s possible that your fuel pump will go bad sooner rather than later. United Diesel Repair is going to list the signs of a bad fuel pump in your diesel engine below.
Constant Overheating
One odd thing that happens when the fuel pump malfunctions is that your engine overheats constantly. This is because the fuel pump motor is overheating and transferring the excess heat into the engine. The fuel pump actually uses the diesel fuel to keep the motor cool. If it isn’t drawing enough fuel from the tank, the motor will overheat.
Difficulty Starting the Engine
Another sign that your fuel pump is going out is if it is more difficult to start your engine than usual. Yes, diesel engines crank a few times before they fire up, but you should be able to get your engine started. If you are finding it nearly impossible to get the diesel engine running, there’s a strong chance that the fuel pump has died and there is no diesel fuel in the engine.
High-Speed Engine Sputtering
As with gasoline-powered engines, your diesel engine needs more diesel fuel when you drive it faster. If the diesel engine is not being supplied with the necessary fuel, it will begin to sputter and suffer at higher speeds. Unfortunately, you will continue to have this problem until you get the fuel pump replaced.
Stress-Induced Power Loss
The same is true when your diesel automobile is under stress. If you are driving a diesel truck that tows a trailer, you may notice that the engine loses power when the trailer is attached. This is a sign that the pump is not pushing enough fuel through to the diesel engine.
Low Diesel Fuel Pressure
The fuel pump regulates the fuel pressure, and if the pump is dying, you will end up with low fuel pressure in your diesel engine. Testing the fuel pressure will indicate the health of the fuel pump.
Reduction in Fuel Economy
Finally, because your diesel engine is not running efficiently, you will notice a reduction in your diesel fuel economy. As with the other symptoms listed above, you will continue to have poor fuel mileage until you replace the faulty fuel pump.
