my jeep is an 89 118k original miles straight six 4.0 and refuses to start in the rain or rainy weather. everything is working normal cranks normal, the works its has got to be something electrical i would assume.... the alternator, battery, battery cables, distributer cap, rotor, plugs and plug wires are all new. its timing is on point and it runs amazing when its nice outside. it has come down to either the ignition coil or relay needs replaced, at least thats our next guess. would love some help or advice just rained for 3 days so no comanche just stopped today and she runs fine got two more days till it rains again would like to have it fixed asap haha. thanks in advance for any replys.
