ejndssn Posted September 9, 2011 Share Posted September 9, 2011 have a dilemma :hmm: my 96 XJ(4.0/auto) that the daughter drives she calls me and stated that it just didn’t want to start so I go to investigate and the preliminary indications look good (check for spark good) so I got it towed to the house since that’s where my tools are and she started right up my areas under consideration is the fuel delivery? Suspect fuel filter may be clog could be the original :dunno: going to check that out next, any other :idea: could be greatly appreciated Link to comment Share on other sites More sharing options...
RockMJ Posted September 9, 2011 Share Posted September 9, 2011 More than likely the CPS (Crank Position Sensor). These are notorious for going bad and when they do the Jeep will not start. Generally speaking when things like this occur you just run down the check list of fuel, spark, and air. Ive had several XJ's leave me stranded because of the CPS. Hope that helps RockMJ Link to comment Share on other sites More sharing options...
jimoshel Posted September 9, 2011 Share Posted September 9, 2011 When the CPS goes out , you don't have a spark. I suspect fuel flow problems. However you are correct in blaming the CPS for a lot of no start problems. I have a '89MJ that constantly, about every 2-300 miles won't start. I just unplug and replug the CPS and it fires right up. I've cleaned the connectors and every thing I can think of and it still does it. Been doing it for 3 years now. Link to comment Share on other sites More sharing options...
Pete M Posted September 9, 2011 Share Posted September 9, 2011 Jim, when you cleaned up the connector, did you squirt in a bit of dielectric grease? Link to comment Share on other sites More sharing options...
