EFI fuel pump... no worky???

picked up an EFI fuel pump from a friend and bench tested it today. well, it kicked on (wired straight from a car battery) but wouldn't pump any fuel out of the gas jug. can it kick on but still be bad?

just wanna be sure before i have to buy a new one for $100

 

Reverse the wires...

 

ill do that first thing in the morning.... thx Gene

 

I think Gene nailed but to answer your question depending on what type Vane/gyro etc....it can run and not pump.....

 

the pumps suck and sucking. they need to be gravity feed. so try puting the pump below the fuel source.

 

I had one from an F150 go bad like that. I bought it at a junkyard for my 2.3 swap. Worked great at first, then started losing pressure, until it just quit pumping all together. Still ran though. Just went and bought a new one for 90 bucks..

 

im gonna try switching the wires on it today. if that doesnt work, i may put an electric fuel pump for a carb in front of it to act as a 'feeder'. we'll see what happens

 

just wired it up the other way and still no worky. guess ill just go buy a new pump....

 

I had one that wouldn't pick up at first. I jiggled it arround a little cause I imagined it had an air pocket and it started working all of a sudden. Startled me when it did...

 

well i done everything that i knew to do to it so i just went and bought a new pump at the local advance and now it works fine


thanks for the helps guys

 

I told you you needed a pump...

 

Gene.... go to bed
