I attempted last night to rebuild my failing fuel pump with an Airtex 3240 pump. Everything went together just fine with the exception of the power plug (it fit, but didn't fit perfectly).
I put the rebuilt pump in... and when I turn the ignition switch to on, I hear the pump activate, However it isn't actually... pumping. I have 0 fuel pressure now.
Any ideas?
The only thought I had was that possibly the +/- terminals are switched and it isn't pumping like it should.. but this doesn't seem like a probability.
Thanks in advance

Will check polarity tonight. (since I can't source a $100 fuel pump assembly locally I attempted to rebuild since many other have done this with success.. why throw away the entire thing when the failing part can be replaced).

There is nothing wrong with replacing just the pump. I don't understand these guys that say "you can't just replace the pump'. Like there's some magical relationship between each individial pump and its housing and putting in a new pump will put a curse on the "magic". The engine and housing don't know nor care what pump is in there. But I digress.....
How's your fuel filter? If its been a while I'd pull it off and see if you get fuel pumping with it removed.

Who says you can't? I said I wouldn't. And based on recent threads, the reason is obvious.
Maybe that AirTec is a POS. There are plenty of other pump brands out there.

The fuel line on mine popped off after I installed the Airtex. I mean the fuel line inside the pump housing. The hose must be high pressure and the clamps must be for fuel injection systems. Fortunately, after you've taken it out a couple of times it gets easier. ;^)

I have found that with electrical connections, there is no such thing as described above. Usually a poor fit is the first reason for anything electrical not to work.
My early 97 has the hundred dollar complete fuel pump assemly as well. Mine required complete replacement due to the top plastic cracking. But even so, I would go with the complete assembly over rebuilding those.
