I have a 04 Wrangler X 6cy 5sp manuel. It will not start when the weather is cold. It will crank fine and strong but just wont fire. I'm not getting any codes. When this happens there is not reading on my battery gauge, fuel pump is not cutting on. The battery has been replaced along with the crankshaft sensor, both have not fixed the problem. Battery cables are in good shape no corrotion anywere. When the weather is warm it fires up and runs just fine. I've read alot of "no start" issues and was wondering if anyone had an idea of were to start?
