Is Your Car Stalling? Maybe Your Fuel Pressure Regulator Is The Problem
Most car owners depend on their cars to get them to work, but what happens when your car begins to stall? Your car may not be as reliable as it once was. Thankfully, you can do something about it on your own, especially if the problem lies with your fuel pressure regulator.
Signs That Your Pressure Regulator Is Faulty
The fuel pressure regulator is a small mechanism in your vehicle's fuel delivery system that helps control the amount of fuel that your engine receives. This regulator uses springs and hoses to ensure that excess fuel is pushed back to the fuel tank.
A faulty fuel pressure regulator can halt the amount of fuel that your engine receives and cause your car to stall. But, a defective fuel pressure regulator can halt fuel or overload your engine with fuel. Insufficient or too much fuel can cause some of the following:
- Spark plugs can appear blackened because there is too much fuel in your engine.
- Your car may idle roughly because of the unbalanced fuel-to-air mixture.
- You might see black smoke coming from the tailpipe because there is unused fuel in your engine.
- Your oil dipstick might smell like gasoline because there is too much gas in your engine.
- The vacuum hoses might end up having some gasoline leakage from the engine.
- Your car might end up consuming more gasoline than it normally would.
You can talk to your auto care specialist about these signs to help confirm your suspicions, just in case.
Replace Your Own Fuel Pressure Regulator
You will need the following to replace your regulator:
- Your owner's manual or repair guide
- Safety goggles and gloves
- A new fuel pressure regulator that matches your car
- Socket and wrench set
- Park your vehicle in a safe location.
- Put your gloves and glasses on, and open up the hood of your car.
- Locate your car battery, and disconnect the negative or red cable for your protection.
- Find the fuel pressure regulator, which is a small hexagon-like mechanism that usually sits in the back of your vehicle. You can use your owner's manual or repair guide to help you find it.
- Carefully remove the small hoses and plug-like connections from the fuel pressure regulator.
- Use your socket and wrench set to remove the screws holding the regulator in place. Remove the regulator, and replace it with your new one.
- Secure the new regulator in place using the screws, and reconnect all the cables connected to it.
- Now you can reconnect the red or negative cable back to your car.
Remember that you can have your auto care specialist deal with this problem if you feel uncomfortable with any of the steps above.
