well ive been working on my 93 GC for a while now and its been really cold here twice ive replaced relays dropped my tank and checked the pump. both times i did that i was in a nice warm shop and the jeep started just fine after getting it buttoned up. i would drive it home and try to start it the next day and nothing. so this time i replaced the Crank positon sensor. i had already done the hair dryer test to the ecu and no fix so im hoping that this fixes it.

 

Well went back three hours late in 10 degree weather and the jeep started up like a champ you cant keep a good jeep down

 

They were a lot simpler without all the electronics to worry about. Thank you EPA!
