The fuel pump that was installed when your vehicle was assembled in the factory will last about 100,000 miles. After this milestone, you may start to experience engine problems that we will list below. These problems indicate an issue with the fuel pump. Trinity Automotive can test your fuel pump, and if it is malfunctioning, we can replace it.
An Overheating Engine
It might seem strange that a faulty fuel pump can overheat your engine but it can. The fuel pump has a motor of its own that uses gasoline or diesel fuel to keep it cool. If the pump is not drawing enough fuel out of the tank, the motor will overheat. This excess heat will cause your engine to overheat.
A faulty fuel pump can also make your engine sputter at high speeds. This is because the engine requires more fuel under these driving conditions. If it does not get the fuel it needs, it will sputter and struggle to maintain the higher speed. You will continue to have these problems until you replace the fuel pump.
Reduced Fuel Pressure
You might also end up with a reduction in your vehicle’s fuel pressure if the fuel pump is not generating enough of it. You can test your fuel pressure by purchasing a gauge specifically for this task. If you would prefer, we can test your fuel pressure to see if it is within the limitations as specified by your vehicle manufacturer.
Reduced Gas Mileage
Naturally, if the engine is not getting the right amount of fuel, it is not running efficiently. When this happens, you end up with a reduction in your vehicle’s gas mileage. This can be frustrating with gas prices what they are these days. You don’t need to fill up more often.
Stress Power Loss
Your vehicle will lose power if the fuel pump cannot supply the additional gasoline needed when the engine is under stress. Things that stress out your engine include driving up steep inclines, overloading your vehicle, or towing a trailer behind it.
Finally, because the fuel pump supplies the fuel to the engine, if it is inoperable, you will end up with a dead engine. Without an operating fuel pump, the engine receives no diesel fuel or gasoline.
