97 TJ Compuer Broken?
The fuel gauge on my dash does not work at all. I have an autotap scan tool which can read the fuel level from the computer which indicates that the sending unit is fine. I performed TEST3A from the Jeep Diagnosis manual I have and the fuel level moves and goes through E,1/2,F as it should. All the other gauges in the instrument cluster work fine. Does this confirm that my computer (PCM) needs to be replaced? If so, should I do it myself or take it to the dealer?
