How To Diagnose And Fix Fuel Pump Problems in Your BMW by College Station Mechanic?

Thus, the engine needs the right amount of air and fuel for running smoothly. To fulfill the fuel demands of the engine, the BMW has several important components. Among these components, the fuel pump is the most vital one that can take fuel from the fuel tank and sends it to the engine to start and run it.

In general, the fuel pump of the car should last for at least 100,000 miles or more. Over regular use, the fuel pump of the car is overheated or damaged. As a result, the engine is unable to get the right amount of fuel to run properly.

When it happens, you have to consult with a reputed auto repair shop to diagnose and fix the fuel pump issues in your vehicle. The following points define the way to diagnose them and fix the fuel pump problems in the BMW.

Reduced gas mileage

When the valves in the fuel pump of the car are damaged, you will find that you have to fill the fuel tank more often than required. Thus, the valves of the fuel pump are opening or closing at the right time for handling the gasoline flow into the engine system.

If the valve is not closed at the right time, the fuel pump is sending too much fuel to the engine than required. As a result, the excess gasoline doesn't use within the engine and burns up unnecessarily. Left it untreated for longer can reduce the gas mileage of the car.

Overheating and sputtering engine

If the fuel pump in your car is overheated for any reason, then it will overheat the engine ultimately. Eventually, you will find that the overheated fuel pump will stall out the engine and burst the several engine components.

On the other hand, the failed fuel pump also causes sputtering when the engine starts because the clogged fuel pump is unable to deliver the right amount of fuel to the engine and the starvation of fuel will cause engine sputtering. Moreover, these problems are commonly arising in your car if the engine hit the top speed on the highway.

Loss of power or low fuel pressure

Due to the failed fuel pump, you will notice that the power of the engine is reduced while carrying a heavy load. If you are putting more loads on the engine, then the fuel pump is unable to deliver the right amount of fuel to fulfill the fuel demands of the engine and run under stressful situations.

Apart from the power loss, the failed fuel pump also reduces the fuel pressure of the engine. When it happens, you have to test the fuel pressure by a fuel pressure gauge and read the pressure by revving the engine.

Trouble starting

Moreover, the starting problems are arising in your car for numerous reasons such as a dead battery, bad alternator, worn starter, and a failed fuel pump. When the fuel pump is failed, the engine is not getting the right amount of fuel into the combustion chamber to start the car.

As a result, the engine cranks over when you turn the key, but doesn't start at all. Without resolving the problem, if you start the car with less amount of fuel, then it will drain the battery power and put more stress on the starting system which can lead to costly repairs.

Whining noise from the fuel tank

If the fuel pump is beginning to fail, then it will produce a loud whining noise from the fuel tank while running. Subsequently, the contaminated fuel tank or the low amount of fuel in the tank can't deliver necessary fuel to the engine and produce a whining noise.

So, when you will hear a loud whining noise from the fuel tank of the BMW, take it to a mechanic as soon as possible for proper repair or replacement.

Conclusion

All we know is that the clogged fuel pump in the BMW cannot deliver the right amount of fuel to the engine. When it happens, the engine faces trouble starting and causes many problems. If you don't resolve the problem at right time, it may clog the fuel lines and end up with a dead engine.

Due to these reasons, you have to keep the fuel pump in the good condition. If you found that the fuel pump of your BMW is damaged while driving on the roads of College Station, then bring it to your nearest mechanic for proper diagnosis and repair/replacement.
