For 5 years My XJ displayed the Check Engine Light & no one could locate the problem until I noticed a sizeable fuel leak while on a trip. I took it to a Dodge dealer in Tucson,they replaced the fuel pump,cleared the codes and we drove to Pennsylvania & returned w/o the check engine light displayed.My mechanic was advised of the corrections , he told me every XJ he's worked on has had the check engine light on and nothing is listed in any of the jeep tech manuals about the fuel pump emission leak problem.
