So I have owned my Jeep TJ for about two 1/2 years now. When I brought my Jeep the guy had told me about a over heating problem the Jeep has had. He had changed the radiator to a aluminum radiator, changed the Fan blade and the fan clutch. The fan blade he installed was a plastic fan blade from another car. I had to replace the cooling temperature sensor and that sloved the over heating issue. I have also change/ replace the radiator, fan blade and clutch back to original. But here is my problem now. So if I driving the jeep around on a hot day and I enter a store for 10 to 15 minutes come back out and try to start the jeep up. It will not want to start. The Jeep will crank but will not start up. I will have to wait like about 20 minutes and the jeep will start up. Funny thing is that this doesn't happened all the time. I've even covered the fuel rail thinking about the heat from the engine causing a vapor gas lock do to the amount of heat. Has anyone ever experienced this issue with there Jeep TJ????
