TURN YOUR KEY TO THE ON POSITION AND LISTEN FOR A HUMMING SOUND FROM YOUR TANK OR TAKE FUEL FILTER LOOSE TO SEE IF ANY GAS IS FLOWING THROUGH IT. FUEL FILTER IS LOCATED UNDER THE HOOD, NEAR THE BRAKE RESEVIOR
I can tell you the fuel pump is in the gas tank.
No, you need to check fuel pressure and the power and ground wires at the pump.
how do you tell if your fuel pump is working
You can tell if your fuel pump shutoff switch is bad, if the fuel pump does not shut off when you flip the switch. You can also tell if the switch is bad by looking at the wire connections.
1. you should be able to hear it running 2. there is a schrader valve on the fuel rail, connect a fuel pressure meter to it and check your fuel pressure.
well if you have fuel and a new filter a good fuel pump relay and the wires going to the fuel pump have power and no fuel pressure you need a fuel pump
A fuel pressure test done at the fuel rail will verify the condition of the fuel pump. Before going to that much trouble check the fuse, and fuel pump relay. If either one is defective the fuel pump will not function.
You will have to remove the fuel pump relay or the fuse for the fuel pump. You did not say what year it was, so I can't tell you where it is. SORRY.
Sounds like you've either got a clogged fuel filter or a defective fuel pump. Can you hear the pump run when you turn the key on? If not, the first things to check would be the fuse and relay for the fuel pump.
Have the fuel pressure checked. If the pump is noisy it is failing. do not forget to replace the fuel filter. A clogged fuel filter will appear as low fuel pressure, and overwork the pump.
You can test your automotive mechanical fuel pump with a diagnostic tester. The diagnostic tester can tell if the fuel pump is operating properly.
A fuel pressure test can determine if the pump is working properly or not.
If you hear the fuel pump run that is a good sign it is working however, a fuel pump pressure test would tell you if the pump is meeting the required pressure.
If you hear the fuel pump running, then start by replacing the fuel filter. If you don't hear the pump, check the fuse. A fuel pressure test will verify if the pump is good or not. It can also be a fuel pump relay or in rare instances a defective ECU.
do fuel pressure test
i am looking for fuel pump for 99 Chevy Malibu where fuel loacation please tell me now
Get the pressure and fuel delivery spec and test the pump for pressure and fuel delivery rate.
When u turn key on , you should hear a humming for a few seconds. this is the fuel pump priming (sending fuel up the line). If you don't hear it, fuel pump is not working.
try bypassing the fuel pump, and directly injecting fuel, this will tell you if the problem is the pump, the lines, or further ahead
Have a helper stand at the fuel filler door with the fuel cap off and listen carefully. Turn on the ignition without starting the engine. You should hear the pump run for a few seconds and then shut down. If not, check the fuel pump fuse & relay. If they are good the pump is more than likely defective. Even if the pump is running that does not mean it is pumping fuel. The fuel filter can be clogged or the pump can be bad and still be running. A fuel pressure test at the fuel rail will verify the condition of the pump. Replace the fuel filter first thing if you have not done so in the last 50,000 miles.
Check your fuel pressure at the fuel rail. If the pressure is low, and your filter is not clogged, fuel pump is likely suspect.
Simple, replace the fuel filter and if it still will not start more than likely the fuel pump is defective. But it can also be nothing more than a blown fuse or defective fuel pump relay. Check them both before moving to replacing the fuel pump.
Most likely located in fuel tank
Have a fuel pressure test run by a trusted mechanic.
How Can You Tell If The Fuel Pump Relay Switch Is Bad? Have a mechanic do a fuel pressure check this will tell you if the pump is working properly or on most vehicles you should be able to hear the pump kick on. You can also have the wiring checked to see if the pump is getting power...
