My 1999 cherokee sport [XJ] is having ignition / starting problems. When I try to start the key lock symbol appears in the dash read out, and the car wont start. Turns over a treat but wont fire. Have been told by a jeep dealer that the problem is the key reader,or skimmer does not recognise the key,and wont allow the fuel pump
to work,, no fuel ,nostart. So,, we replace the ignition barrel,and the skimmer,and the key,,reprogramme them all,and things go well, for about 5/6 starts, then nothing again. Problem however is intermittent,,,.. So,, is/was the initial diagnosis wrong, and if so ,what might I do to fix it??? HELP PLEASE, if possible..
