Where Should you go in Plano to Repair a Failed High-Pressure Fuel Pump in a BMW
by europewpadmin April 3, 2021The BMW brand is an elite class of its own, with sleek designs and sophisticated interiors that are a true icon of the roadways. Over time, wear and tear will cause certain parts to break down and need repair. The high-pressure fuel pump is one of such parts.
Let’s dig into the purpose of the high-pressure fuel pump, symptoms of high-pressure fuel pump failure, how to prevent it, and where to go when your high-pressure fuel pump is giving you problems.
Purpose of the High-Pressure Fuel Pump
The high-pressure fuel pump is responsible for compressing the fuel supplied by the fuel pump to the fuel injectors for distribution to the engine. Without it, your vehicle cannot move gas from the tank to the engine, meaning your engine will not turn over when you try to start your car. Without a fuel pump in working order, you essentially cannot drive your car.
Symptoms of High-Pressure Fuel Pump Failure
If you sense something is wrong with your fuel pump, it is imperative you take your BMW in for service as soon as possible. Total fuel pump failure means you will not be able to drive your car, so it’s best to get the issue taken care of before it gets worse.
Here are the most common symptoms of high-pressure fuel pump failure:
- Lack of Turn Over: Your engine will struggle to turn over if your fuel pump isn’t working. Engine combustion requires a mix of air and fuel, as ignited by the spark plugs. Without your fuel pump in working order, the combustion process cannot work as it should to turn your engine over. Driving your car is therefore impossible.
- Poor Acceleration: A rush of gas is needed to provide the extra power to accelerate your vehicle. With a failed fuel pump, your vehicle will struggle to accelerate, and may even sputter or stall when you put your foot on the gas. This can be dangerous when driving on high-speed roads.
- Engine Sputtering: Your vehicle will sputter at high speeds due to the fuel pump unable to supply the gas needed to maintain the high speed, which can be dangerous while on high-speed roads.
How to Prevent High-Pressure Fuel Pump Failure
Staying up to date with preventative maintenance for your BMW according to the owner’s manual is a sure-fire way to avoid parts failures. You may not see anything wrong with your vehicle at a glance, but by taking it in for routine preventative maintenance, your mechanic will be able to catch any issues early on before your fuel pump has a chance to fail.
Keeping your tank full or at least over halfway full can help prevent fuel pump failure. Because your fuel pump is an electrical component, it can become hot and overheat when your gas tank is low. Keeping at least a half tank of gas in your fuel pump helps keep it cool.
Using quality fuel in your fuel pump is a must to keep it in good shape. Always stick to name brands and remember that you get what you pay for when it comes to gasoline. It’s worth it to pay more for quality brands and avoid costly repairs that will likely cost you more in the long run and not worth the savings of cheap gasoline.
If you have flexibility in your schedule, check with the gas station attendant regarding the most recent delivery of gasoline at the pumps. A fresh delivery is more likely to have dirt, debris, and other contaminants swirling about that will inject into your gas tank. These can contribute to fuel pump failure. Waiting at least a few hours after a fresh delivery is a safer bet.
