New Fuel Pump Assembly - Gauge messed up
Greetings.
This is a proxy question— my buddy has my old XJ and just put a new fuel pump assembly: https://www.quadratec.com/products/51306_0147.htm into it and it's giving him grief. it's a 1996 XJ Country / 4.0L / AW4 / NP232 / 4DR / oval connectors all around I think This is what he chatted me: since i put in that new fuel pump assembly the fuel pump float isn't reporting correctly to the computer i think like it doesn't show it as full and it doesn't put the light on when it's close to empty do you know if that is a setting in the computer that needs to be reset? I've never heard of having to reset the ECU, so I doubt that's the culprit. And since it can only go in one way, it's not the orientation of the unit. Any ideas? Most of the results I got trolling old problems like this were that people replaced only components of the unit, i.e. just the pump and not the whole assembly. I've never heard of Crown making their own electrical crap. Is this just a white-label chinesium product? Should he RMA it and get a different one? Thanks, all. |
I just did the Crown assembly on my 96 as well. There are 2 issues to look out for:
1. The Crown assembly will not position the float as low in the tank as the factory assembly. The result is that when the tank is full, the gauge will read around 3/4 full. When the gauge is on E the tank will have 5-7 gallons in it. I could open it all back up and bend the float arm down so that its resting position is similar to the factory assembly. Thus far, I have not opted to open it back up. 2. The connector was a little problematic. It was getting hung up on the molex weatherproofing gasket. Initially this led to some strange problems where the pump would work for a bit, and then on the next start there would be no power to the pump. It took me a little while to realize that the connector was not even close to being fully closed and locked. I tried to use picks to get the connector weatherproofing gasket in position, but just couldn't get at it. Eventually, I used an oil filter wrench (like pliers, but with a very wide mouth) to bring the two sides of the connector together enough to lock the connector. After that, I did not have any connectivity/power issues. When the time comes to disconnect it - its going to be a pain I'm sure. I do not have the near-empty indicator on my dash, so I can not speak to that I'm araid. |
Thanks, dude! I think that about sums it up. Guess it's caveat emptor for the Crown brand...

Yes, it would have been better if everything was to factory spec, but after some of the horror stories I read on reviews, the Crown product did what I needed it to do. Not like us 96ers have a lot of choices on this particular part any way. |
