Do you have a fuel pump in your car that you think is going bad? You may have signs like reduced gas mileage, odd behavior when driving, or even a car that will not turn on at all. It will help to do the following 3 things to troubleshoot the problem.
Check The Fuse
The first thing you'll want to do is investigate what could be the easiest problem to repair. Take a look at the fuses in your vehicle and verify that the one for the fuel pump isn't blown. The piece of metal in the fuse should be continuous to verify that it is still in good condition. If it looks good, you know it is not a blown fuse.
Look Out for Sudden Power Loss
One common situation where a fuel pump gives out is when it has a lot of stress put on it. This is typically when you are going up a hill, accelerating quickly, or towing something heavy behind your car. If this is when you are noticing the signs of the vehicle losing power, it is due to the fuel pump not being able to keep up with the demand you are asking of it. Another time that the engine may lose power is when you are driving at high speeds. The engine may act as if it is sputtering, which is due to the fuel pump not working as it is intended.
Use A Fuel Pressure Gauge
A good way to check the fuel pump is to use a fuel pressure gauge. It's a pretty cheap tool that you can buy from your local auto part store, so it won't set you back that much. The fuel pressure gauge also works on every car, so it may be useful in the future. Check your owner's manual for where you would connect the fuel pressure gauge to your car underneath the hood. Then you start up the car and look at the gauge. If there is not any pressure registering on the fuel pressure gauge, you'll know for sure that the fuel pump isn't working at all.
Still not sure if the fuel pump is in good condition? Take your car to a local auto repair shop and have a mechanic look under the hood for you. They'll be able to diagnose your problem and let you know what you need to repair to get back on the road again.
