I have a 1997 4.0 Sport. It sat for four days, and then this morning would not start at all. It sounds like it wants to turn over, and comes close, but nothing.
A friend came over and tried helping, but it is a little dark out already, he will check it out again over the weekend. I can hear the fuel pump coming on, and he tried spraying some starter fluid into the air box and still nothing. Also checked the spark plugs and although oily, they definitely had spark (he shocked himself by accident while holding the plug wire).
Battery and starter are both fairly new. Starter last December, battery (optima yellow top) in January. I do not know when but the plugs, wires, and distributor cap were also replaced fairly recently. (I have only had this wrangler for a few months, and it has been a money pit. But I still love it to death)
It has run like a champ since I got it. I did have two issues with it, one was an issue with an immobilizer system, and the other was that it was running a little hot. But that turned out to be a simple fix, the hose clamp was put over the hose and not over the metal part, restricting the coolant.
I do not know if it matters either, but it is a Euro specs Jeep, although the only difference I have been able to find has been the gauges have MPH and KPH...with KPH on top, and the immobilizer is standard in Germany. It is able to be shipped back home to the States when my tour here is finished (Army)
My knowledge of cars is minimal, I can change oil, and brakes... that is about it. My friend knows much more, I am hoping someone may have an idea that I can pass onto him.
Thank you for any help you are able to offer
