How's it going everyone. So here is my problem.. go to start my Jeep and sometimes (more times than not) the motor makes a crank noise like it is trying to turn over (almost like a discharged battery crank) and it will keep making the noise until you let off the key.. Go and try and crank it again she fires right up. And than runs and drives perfectly. Idles just right. It doesn't seem to do it when there is moisture in the air like after a rain storm or during a rain storm. <--Weird

So here is what I have already done... tried a new battery, replaced starter, replaced positive and ground cables from the battery to the block and down to the starter, cleaned the ground connections on the block and inner fender panel... I think that is it... Any ideas would be greatly appreciated...
