simply dissconect the "in hose" on your fuel filter while the car is off. Once this is done turn your engine on you should A. hear your fuel pump pressurize the system B. see the fuel pumpin out of the tube in your hand @ about 30+psi.. if neither of these things occur your pump is pooched.fuel filter is located under the hood attached to the fire wallupper passengerside. 10 min tops
if you don't already have a manual, buy one, they are helpful and can tell you how to test things like that. there are other things worth checking first, like the fuel filter, which is cheap and if you havent replaced it, i recommend doing so it depends on what the car was doing that makes you think your fuel pump might be out
Fuel pump pressure test.
The 2005 Honda civic is fuel-efficient and has environmentally friendly engines and roomy interior. It has impressive crash test scores. The anti-lock brakes are not available on the DX or LX models.
Test Drive - 2002 Honda Civic Si was released on: USA: 15 November 2005
Fuel pressure test at the fuel rail.
A fuel pump pressure test could determine the condition of the fuel pump and fuel system.
You can test your automotive mechanical fuel pump with a diagnostic tester. The diagnostic tester can tell if the fuel pump is operating properly.
You will need a helper. Have the helper sit in the drivers seat while you stand at the fuel filler door with the door open and fuel cap off. Have the helper turn the ignition switch to the on position but not start the engine. As you have your ear close to the opening to the fuel tank you will hear the pump come on and run for a few seconds and then shut down. Repeat this as necessary to determine that you actually hear the pump run. If you hear the pump run it is more than likely good but it is possible that it could run and still not be pumping fuel. The only way to verify this would be to run a fuel pressure test with a fuel pressure gauge. If you do not hear the fuel pump run then one of 4 things is wrong. Either there is a problem with the wiring, the fuel pump fuse is blown, the fuel pump relay is defective, or the fuel pump itself is defective.

Where is the fuel pump fuse and relay on 1994 BMW 525i and how can I test to see why my fuel pump won't work
to replace the fuel pump on a 93 Honda civic its quite simple really you can do it yourself first take out your back seat. there is a bolt behind the middle seat between the back rest and the seat. feel around for the bolt and take that out. you should then be able to remove the seat bottom. there is a plate with 4 small screws covering the fuel pump, take that off. remove all electrical connections and hoses. remove the 6 or so nuts that are holding the fuel pump down in place. simply pull the assembly out (carefully you don't want to rip the gasket) then take it to your bench and test it to make sure it is a fuel pump. then rebuild it with new parts. got to love Honda for making a car that you don't have to drop the tank to do this. i recommend picking up a haines manual for that car just so you have the proper guide to look at. hope this helps

Fuel Pump fuse, relay, fuel filter, and all connections. A fuel pressure test will verify a defective fuel pump, or if it is simply not running, and has current to it.Fuel Pump fuse, relay, fuel filter, and all connections.

No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
no idea i hope i helped
Take it to AutoZone, and they can test it
A GOOD FUEL PUMP PRESSURE IS NEEDED
Have a fuel pump pressure test done.
If that is throttle body fuel injection, there is no fuel pump test port. You have to fabricate with some fittings and tap into the fuel line at the fuel filter.
Fuel pressure test. First thing to do is replace the fuel filter. If that does not help, then test the fuel pump with a fuel pressure tester. If you can't hear it run for a few seconds when the key is turned on, either the pump is bad, or the fuse is blown, or the fuel pump relay is defective. Even if you hear it running, it may be so weak as not to work properly.
You can test the fuel pump by touching the positive wire on the positive post of the battery. You will need to ground the ground wire.
I believe this question is related to fuel pump pressure testing...... these test are done by scanning ecu
If you have power to the fuel pump and it will not run it is defective. If it runs but a fuel pressure test verifies that the fuel pressure is low and you replaced the fuel filter then the pump is defective.
