i just put in a walbro 255lph fuel pump and i dont hear a humming sound from the pump. i dont actually want to start the car since i havent finished up the turbo. i was told that i am supposed to hear the fuel pump humming constantly when the key is in the on posiiton, all i hear it is for about 2 seconds and then no more sound. is this normal when the key is on the "on" position?

 

anybody?

 

can somebody answer this?

 

I just went to my car, turned the key to the on position, heard my pump and then it stopped.. So I guess its like primed up and ready to work lol.

 

thanks alot realtyper2!

 

yeah, when i turn to the "accessory" position, i hear THUD THUD THUD THUD then quiet...
