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.
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
I can tell you the fuel pump is in the gas tank.
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.
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.
have you checked under the rear seat? just remove the cushion and you should be able to tell if is there or not.
Do a pressure test. We need to know what engine you have to give you the pressure specifications.
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
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).

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
Check your fuel pressure at the fuel rail. If the pressure is low, and your filter is not clogged, fuel pump is likely suspect.
If you do not hear it run for a few seconds after turning on the ignition without starting the engine, then either the fuse is blown, relay is bad or the pump is bad. If you do hear it running, then it may be weak or the fuel filter may be clogged. You may have to listen at the fuel filler door to actually hear the pump. Replace the fuel filter and then run a fuel pressure test at the fuel rail. If you have no or weak pressure the pump is bad.
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
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...
