How to Check Your Fuel Pump Method 1 Performing an Electrical Test 1.Check the fuel pump fuse. Often, it's not the pump itself that fails to function, but the power that supplies it. Check in your owner's manual for the location of the fuse box, then find the fuse that corresponds to the fuel pump. Pull it out and inspect it for signs of failure. If the fuse is blown, it will be broken or burned. If it looks good, check the rest of the fuses related to the fuel system for signs of being blown and replace them, if necessary. If no fuses are blown, have a helper turn the key while you listen for fuel pump relay clicking on.

If no fuses are blown, have a helper turn the key while you listen for fuel pump relay clicking on. If you need to replace a fuse, make sure you use one with a proper amp rating, never installing one with more amps than necessary. If you find a blown fuse, that might be a sign that you've got a high amp draw and you need to check the individual circuits.Try to replace the blown fuel fuse and try and start vehicle. If the fuse blows again, a direct short is present and will need to be diagnosed. Take your car into the shop to get it checked out. 2.Check the voltage at the pump itself. Just because you're getting juice from the circuit doesn't mean that it's getting to the pump itself, which makes it important to check the voltage there as well. Check out your vehicle's service manual to find out where to check and the proper procedure for checking it. Test for source voltage, to determine whether or not the good charge that's leaving the fuse is getting to the pump. If no power is making it to the fuel pump, then check the fuel pump relay circuit. You could have a bad relay. 3. Perform a drop test using a voltmeter. Check to make sure that the power wire shows the full voltage and the grounding wire shows that it's grounded properly. If this electrical test reveals nothing, it's likely that your fuel pump is the problem and it will need to be replaced, though you can check more thoroughly by completing an additional pressure test. If you show more than one volt difference, that means you've got a problem with corroded wires, or that you've got issues with the circuit on either the positive or negative side.Take it into the shop for further testing and advice. Method 2 Performing a Fuel Pressure Test 1.Eliminate the filter as a possibility. If the filter gets clogged with sediment, you can have trouble accelerating and might suspect your fuel pump has got a problem. To check it, remove the filter from the vehicle and drain excessive fuel from the filter. Use a short piece of rubber hose on the filter inlet. Blow through the filter inlet, paying attention to the resistance, which should be minimal. Inspect the screen for debris and replace the filter if necessary by blowing through the outlet side of filter into a white rag or towel. 2.Get a fuel pressure gauge. Commonly available at most auto parts stores for $20-30, a pressure gauge is a good investment, useful on most makes and models of cars. If you don’t want to buy one, you can also often borrow one from machine shops or auto shops who have them to lend. The test only takes a few minutes. 3.Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches. Different gauges may have slightly different instructions, and the location of the fuel pump varies from vehicle to vehicle, so consult your owner’s manual for more specific instructions. 4.Have a helper rev the engine while you check the gauge. Let the engine warm up slightly, then check the pressure both at idle speed and at the rated speed listed in your pump specifications. If you don’t know the rated speed, just rev the engine and see how the pressure reacts. If you have a serious problem, the needle won’t go anywhere or goes down below specifications, meaning the fuel pump needs to be replaced. The pressure should match the specifications listed in the repair manual, and should increase as you rev the engine. If it doesn’t, you need to replace your fuel pump and filter. Tips If your fuel pump does needs replacing, a rebuilt one is often as good as a new one, and a lot less expensive. If you’re feeling adventurous, some manufacturers supply rebuild kits. You can take your pump apart with a screwdriver and rebuilt it yourself, following directions on the kit. If that idea doesn’t enchant you, ask your service facility to locate and install a rebuilt fuel pump. It should be guaranteed at least three months. Proper precautions should be taken for safe testing and diagnosis. Keep a fire extinguisher nearby while working on or testing the fuel system. How can I prevent my fuel pump from going bad? There are several things you can do to help prevent your fuel pump from going bad: Regularly maintain your vehicle: This includes things like changing the oil and air filter, as well as making sure the engine is tuned up. Avoid running your vehicle low on fuel: This can cause the fuel pump to overwork and wear out prematurely. If you notice any issues with engine performance, it is important to take your vehicle to a mechanic as soon as possible to have it diagnosed and repaired. A bad fuel pump can lead to engine performance issues and even cause your vehicle to break down. Use good-quality gasoline: Using low-quality gasoline can shorten the life of your fuel pump. Be sure to use a good quality gasoline that has the correct octane rating for your vehicle. Keep your fuel tank full: Keeping your fuel tank full can help prevent condensation from forming inside the fuel tank. This can water down the gasoline and cause corrosion. Use a fuel stabilizer: Adding a fuel stabilizer to your gas can help prevent it from going bad. Fuel stabilizers keep the gasoline fresh and help prevent corrosion. Avoid extended idling: Extended idling can overheat the fuel pump and shorten its life. Try to avoid extended idling whenever possible.
