In this video, our decrepit 2004 Impala, "Fred" has died in the driveway in the dead of winter, and is in need of a fuel pump transplant. The fuel pump had been intermittent in the days prior, only working when the weather was slightly warmer. I was able to diagnose the fuel pump as being the culprit by having someone crank the engine over whilst I sprayed starting fluid into the exposed throttle body. By getting it to start on the starting fluid (and it immediately dying afterward) there was simply no need to hook up a fuel pressure gauge or spark tester. Kind of bass-ackward detective work, but the behavior of the vehicle in the days prior raised my hackles.

So you fine YouTubers get to watch as I pop open the access hatch (thank Christ for that "innovation"!) and replace the entire fuel pump module without dropping the gas tank.

I purchased the fuel pump from Amazon, foregoing a mega-expensive Delphi unit and instead going with the highest rated pump that was reasonably priced. This is a deal where I'm only looking to get a few years out of the pump, as the car is getting rusty and racking up the miles.

I also replaced the Fuel Pressure Regulator and the Fuel Filter at the same time, however the replacement of those 2 items will be in the next video.    • 2000-2005 Impala (8th Gen) 3400 Fuel ...  

It has been brought to my attention by several commenters that 2005 model Impalas do not have the access hatch present inside the trunk. I have not been able to confirm yet if this was for all 2005 models, or if there was a specific date range or model availability. I have thusly changed the title of the video to reflect that this should apply to the 2000 through 2004 model years.
