Problem with Fuel Gauge...need advice
 

Hello all,

I recently had a new fuel pump put in my 90 4.0L XJ and my fuel gauge
is not working. I took it back to the shop that installed and they
supposedly checked it out with another gauge which worked so they
thought it was my gauge.

I went to the junkyard and got 2 fuel gauges from a 90 and an 88 XJ. I
pulled out my instrument cluster and installed them and nothing....the
gauge goes all the way past Full to horizontal! I pulled the connector
from the sending unit and it did not go to Full as it should, and then
I read an Alldata that the harness wires #15 and 17 should read 0-88
ohms and it did. The only thing I can think now is that the plastic
circuit board thing on the back of the cluster is bad.

I am thinking about taking it to the dealer but that could be $$$$$. I
have also contemplated getting a whole cluster from another rig and
trying that.

Any suggestions would be appreciated.

Thanks,

LTK

Have them pull the pump, and next time wiggle the float back down
inside the tube it sits in.

Thanks BIll,

It seems lke the shop does want to do too much more with this fuel
pump....I am not sure I am happy with their service.

Is it a relatively easy procedure to extract the fuel pump?

THanks,

You have to drop the tank, last time I did that I swore I'd let
them do it if it's ing the hundred dollar range. And I can understand
how your mechanic lost their patience threading back into place, and
just jammed it in.

Re: Problem with Fuel Gauge...need advice
 

You can get at the connection for the fuel gauge in the front of your
gas tank. I would start there with a multimeter to see what is coming
out of the tank sender and to make sure they hooked up the ground.

'I' think they screwed up. I don't buy the coincidence of the dash
dying at the same time as they were messing with the sender.

Not on his Bill. He has an AMC Jeep with the pump in the front of the
tank. It took Chrysler to pull the drop the tank scam.

Re: Problem with Fuel Gauge...need advice
 

Thanks Mike,

I found on another post that the polarity of the sender was changed in
1991 and even though the new one has the right part number and since
the polarity has changed it will not work. The post said to take out
the pump and reverse the wiring but it will not be accurate since the
resistance is different.

Oh and if you recall I was having problems with stalling and bucking.
I changed my spark plugs to Champions and most of the problems went
away. It still sometimes cuts out but does not stall. When I took it
to the shop to have them "fix" the gauge they said that there might be
a short and it would need to get worse before they could diagnose it.
I was overjoyed to hear that!

Thanks again for your help,

LTK

the polarity has changed it will not work. The post said to take out
the pump and reverse the wiring but it will not be accurate since the
resistance is different.

Oh and if you recall I was having problems with stalling and bucking.
I changed my spark plugs to Champions and most of the problems went
away. It still sometimes cuts out but does not stall. When I took it
to the shop to have them "fix" the gauge they said that there might be
a short and it would need to get worse before they could diagnose it.
I was overjoyed to hear that!

Thanks again for your help,

Re: Problem with Fuel Gauge...need advice
 

Thanks Mike,

I found on another post that the polarity of the sender was changed in
1991 and even though the new one has the right part number and since
the polarity has changed it will not work. The post said to take out
the pump and reverse the wiring but it will not be accurate since the
resistance is different.

Oh and if you recall I was having problems with stalling and bucking.
I changed my spark plugs to Champions and most of the problems went
away. It still sometimes cuts out but does not stall. When I took it
to the shop to have them "fix" the gauge they said that there might be

Re: Problem with Fuel Gauge...need advice
 

If you are willing to pay to get it fixed go to a shop that specialized in
automotive and truck electric systems. All large cities should have at
least one.

If you have a firehouse nearby stop by and ask who does the electrical work
on their rolling stock.

Re: Problem with Fuel Gauge...need advice
 

Well I did it! Went to the junkyard to do some research and found a
number of fuel senders hanging out of old XJ'a and a couple still in
the tank. removed three of them, 2 still had new looking pumps. I
bought a sender and a complete set up for $49 and went home to test
these that were both pulled from a 90 and an 88 XJ.

Success! The Fuel Gauge worked.

Now I needed to unisnstall mine and see what was up. Luckily the
practice at the yard helped a ton!

As I am pulling it out I noticed that the plastic housing of the sender
unit is disconnected from the fuel sender metal body. As I was
extracting the whole unit from the tank the filter boot fell in the
tank! Damn! Hands too big to get in fuel pump hole. Lower the tank to
get it out.

Few hours later...after testing it a few times.....reinstalled and
voila....gauge works!

Thanks for all of your advice,
