I haven't finished getting dressed yet but I decided to turn on my jeep to let it warm up. Wearing only my bra and shorts I hop in the jeep and crank it up, but something is wrong. It almost starts, but then it just on me. I keep trying to turn the key and all it does is crank over and over! What is Wrong with it? Why wont it just start up? I spend 5 minutes cranking over my Jeep.
