Hi, I have a 96 dodge RAM 1500 5.2L V8, so... I've been having problems with the fuel pump for a while now, so I decided to buy a new one, I dropped the tank, put the new one back in, followed every step I was suppose too, well... When i went to start the truck, it just won't start now, so i messed with some things, tried some others, but nothing has worked yet. My brand new fuel pump just won't pump fuel. I manually got all the air bubbles out of the lines, I've tried everything that i can think of, oh and yes the fuel pump turns on when i turn the key, I've poured fuel right down the throttle body, had it running for about a minute, but i had the main fuel line disconnected from the fuel rail with a line coming out of it and into a gas can but there was no fuel being pumped through the line, so i know that for some odd reason It's just not wanting to pump my fuel. Well i sure hope that somone can help me, and thank you in advance.

 

I have the exact same problem getting no fuel to the rail with new pump i put in today. I hear the pump kick on when i turn the key to the on position, the fuel gauge is working. Not sure what is going on.

 

Well I have a suggestion for you, I just got mine all working and everything, the problem with mine was that somehow the power connection to the pump was plugged in, in reverse, so my pump was sucking fuel instead of pumping fuel, I just switched that around, and it started pumping strong, I put everything back together, and now my truck runs like a champ, so you might try what I did

 

Bloody Oar, when you say it was plugged in in reverse, where was that exactly? At the connector on the cover of pump assembly or at the electric pump itself inside the assembly? What brand did you buy?

He's talking about the external electrical connector. Try what he said to do. And what brand did "you" buy? Maybe it's simply a defect. The pumps can run and pump no fuel.
