checking fuel pump

[Ibanezjem7vw]

Is there a way to check the fuel pump to see if it is functional?

thanks

when you turn your key to the start position, you should hear a faint buzzing sound coming from the rear trunk area. this is your fuel pump. however, it can be difficult to hear this buzz/hum over the noise of the engine starting.

what is the problem you are trying to fix? what kind of car do you have? teh more details you give, the more it will help us help you.

sorry about that i didn't notice i left that out. it's a 94 mitsubishi 3000gt. im thinking its the fuel pump or clogged filter because i was driving and the RPM's would drop and it would cut out but it would immediatly kick back on until it finally stopped. i was able to start it a couple of times but it only runs for a couple of seconds. i didn't hear any buzzing sounds when i tried to start it.

thanks

is that the sound thats similar to the active exhaust when you first turn you car on or the fuel pump? i always figured it was the exhaust testing itself on startup or something.

Ok, then let's start at the beginning. Are you getting a Check Engine Light? Did you do any work to the car recently?
