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 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.
If its not pumping.
The best thing to do is replace the fuel filter anyway. You will need to do it even if the fuel pump is bad, so you have nothing to lose. You can listen to hear iif the fuel pump is kicking on at all. If it is, just do the fuel filter. Its much cheaper and easier than the fuel pump. Then you can test the fuel pressure to see if the pump is bad after you replace the filter.
Swap the fuel pump relay with another like relay.
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...
Fuel pressure test. Of course if it is not running, fuse and relay are good then it is bad.
sometimes your car wont start and you will be able to tell when you accelerate..your engine wont get as much gas.You can hear the pump when you turn the key if you dont hear the pump shooting fuel through the lines you have a bad pump.
Swap it with another like relay.
No, you need to check fuel pressure and the power and ground wires at the pump.
Put a fuel pressure gauge on it and that will tell you.
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.
Check your fuel pressure at the fuel rail. If the pressure is low, and your filter is not clogged, fuel pump is likely suspect.
