Hello Jeep Forum members! Glad to be a member but mad about the reason that lead me to seek it out...after buying a used GC for my teenager, I have had nothing but trouble; in a nutshell it has intermittent dying/starting issues and I know when I first get in it whether it will start or not - if I turn the key to the on position w/o actually trying to crank and none of the gauges move, it is not going to start. Also, I will hear the methodic thumping of the cooling fan as it moves at a rythmic beat. I've replaced fuel pump; relays, all sorts of sensors including most recently the CPS. Aside from running better when it runs, it has not prevented the issues and Jeep has washed it hands of the problem, in essence asking me to pay a minimum of 6 hours labor for them to "explore" the problem. I'm beginning to think that it is the SKIM system. Any ideas would be helpful. I've poured over $2,000 into a $2,000 car and I'm at a loss!
