You can expect to get anywhere from 100,000 miles to 150,000 miles out of your Jaguar’s fuel pump. It’s the same if you drive another European make. After this mileage duration, however, RSW European Auto Repair advises that your fuel pump will go bad. Depending on how well you take care of your Jaguar, you may not need to replace the fuel pump for the life of the vehicle. If you notice any of the following symptoms of a bad fuel pump below, however, bring your vehicle to our shop ASAP.
Erratic Engine Surging
Most of the time, your vehicle will lose power if the fuel pump is going bad. This being said, a malfunctioning fuel pump can also release too much fuel into the engine. This will cause your Jaguar’s engine to surge erratically and unexpectedly.
High-Speed Power Loss
As we just said, you may also experience power loss when you are driving at high speeds. This is an indication that the engine does not have enough fuel. The power loss will manifest in engine sputtering. You will also struggle to maintain a higher speed.
Stress Power Loss
Another time your engine loses power with the faulty fuel pump is when it is under stress. You will likely never tow a trailer behind your Jaguar, but if it constantly loses power when you drive up steep hills, this is an indication that the fuel pump is going bad.
Reduced Fuel Economy
A malfunctioning fuel pump can also reduce your Jaguar’s fuel economy. This is frustrating, especially with gas prices getting higher and higher every day. If your Jaguar is getting noticeably fewer miles to the gallon, you may have a fuel pump problem.
Reduced Fuel Pressure
Reduced fuel pressure definitely points to the fuel pump, as the pump maintains the fuel pressure. We’d be happy to check your fuel pressure for you to make sure it is within the desired range. If it isn’t, you need a new fuel pump.
Overheating Engine
One strange side effect of a faulty fuel pump is an overheating engine. This happens because the fuel pump is unable to pull enough fuel out of the tank to cool its motor. When the fuel pump motor overheats, the excess heat transfers into the engine.
Hard Starts/Dead Engine
Finally, you may find yourself unable to start your Jaguar’s engine or having a very difficult time getting it started. The fuel pump has died, the Jaguar’s engine is completely fuel-starved.
Again, call RSW European Auto Repair in Green Brook Township, NJ, at the first sign of trouble. We can test your fuel pump and replacement if necessary.
