My Jeep Grand Cherokee won't start on damp dewy mornings, just cranks like the coil wire is missing. Fires up fine in the afternoon like nothing's wrong.......any suggestions?

 

Check your distriber cap for crack that allowing moisure in it.

 

welcome to df...

check your coil, sounds like it's got an issue. one thing you can do when it's damp out and it wont start is to put a hot air blower (hair dryer) on the coil and heat it up... if it starts, that's your problem, if not, go to the cap & check for the moisture.

 

check the rain gutters i knwo some moddles will actualy divert watter verry close to the distributor cap and if so try caulking around it my buddies mom had a chevy lumina that didthat on wet mornings it wouldent start for the life of it
