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
