Title: JEEP GRAND CHEROKEE - STARTING / STALLING
Post by: bunnykins on July 08, 2012, 08:57:41 PM

my jeep has been going well with no problems for awhile and also passed its MOT last month  :grin:

this is a common problem on mine - after sometime it wont start so i do my usual - take door card off, disconnect door module then it will start and should be okay

but this time after doing that, it stalled twice on a short trip, but started ok and i got home.

i notice that when i start it, it seems to knock for awhile but on 2nd turn of key it does start.

anyone come across this before or think they know what it is ? is it the coil/plugs/points need cleaning ?

thanks in advance.

Did you clean the connections to the module before you reconnected it?

WD40 as been banned in a lot of safety control industry's as it can make them worse
