Fuel Pump Installation gone horribley wrong.

[spankme234]

Today i had my friends step dad install my fuel pump which i bought used but in "good" condition from a nico member. After installation which took 45mins the car would not start. I let it pressurise some more and after 20 more tries got it started. This fuel pump was extremly loud! it made my fuel pump sound like a whisper. After we got it running we went to autozone to pick a few things up for my friends car. After that we went to wendies and when we got back in the car it stalled out and the pump died. We had to get his stepdad to come back with his tools to wendies and help us put my old fuel pump back in which took another 45 mins. I am now convinced that the sound my original pump makes is normal.

How many pumps have you heard? It sounds like you may have only heard 2 pumps, one you thought that was going out and one that did go out. Perhaps you can find another Q45 car similar to yours and ask the owner to listen to it. Yours might still be going out so you may want to try this before it leaves you stranded. They shouldn't be very loud at all, noticeable but not obtrusive.

A good new working fuel pump doesn't make any sound that you can hear! When they start going up, then you start hearing them. Many of us have heard the "buzz" of fuel pumps starting to go bad and many of us have driven our Q's for months with that "buzz". It's been done. The down side to driving with a buzzing fuel pump is that it can leave you stranded as you have found out and you run the risk of burning your Fuel pump control unit out, which has a higher price tag.

I think I drove my Q for about 7 months when I could actually hear a slight Buzz, but it started getting louder and louder so I just changed it. If you do change your fuel pump just get a brand new one. Used ones are not worth it as you have found out.

The noise is not very noticable. The only reason i noticed it was because my back seats are removed right now. Thanks for the advice but i feel confident on driving on this one for now. I'll start thinking about changing it for a brand new one once i hear the noise increasing.

If you heard a noise at all then there was a problem.

I was expecting that the gas tank blew up during the install when I saw the thread...

A properly operating pump should make very little to no noise

Buying a used fuel pump is just plain dumb, no matter it's alleged conditon, unless you like repeating the labor sooner rather than later.

But ... arg ... he said he got it from a NICO member. Shame on him, unless he admitted he had no idea if it was good or not.

Doesn't matter if he got it from JC himself.

No way to predict future life, let alone past wear.

Agreed, buy once - call Joe!

His prices aren't all that bad - and you get the piece of mind knowing that what you installed is the EXACT same part that was in your car when the odometer read "1"

At the metal tabs where u place negative and positive wires the tabs on that one were burnt looking and worn, the tabs on mine were silver and new looking. Oh well lesson learned. And now i am an expert in changing fuel pumps

[spankme234]

Also the original fuel pump was slightly different from the one i bought. I dont know what its called but at the top of the fuel pump their is a head piece that has a hole in it(i think its red?). The fuel pump that i bought had a hole 2times smaller then the original. Could it be it was from a different year and thats why it didn't work?

All 90-96 OEM pumps look the same as far as I know... I suspect it was aftermarket or from a different model.
