To determine if the fuel pump is bad on a 2000 GMC Savana, listen for a humming sound from the fuel tank when you turn the ignition key to the "ON" position (not starting the engine). If you don't hear this sound, it may indicate a malfunctioning pump. Additionally, you can check for fuel pressure at the fuel rail using a pressure gauge; if the pressure is below the specified range, the pump may be faulty. Lastly, if the engine is cranking but not starting, it could also suggest a fuel pump issue.
how do you tell if your fuel pump is working
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.
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.
Do a pressure test. We need to know what engine you have to give you the pressure specifications.
have you checked under the rear seat? just remove the cushion and you should be able to tell if is there or not.
I can tell you the fuel pump is in the gas tank.
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.
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.
The easiest way is to call Toyota dealer and give them your car's VIN number. They should tell you which exactly fuel pump you have (Type A or B).
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.
A fuel pressure test can determine if the pump is working properly or not.
