Jeep Wrangler Forum:Jeep Wrangler TJ 2001 -cranks but won't start

How about checking the timing on the Jeep and have it done properly.  Your spark plug wires may be off by one or two and that could be the problem right there.  If it's not the timing, then it could be your fuel system.  You may be getting the spark and the air required, but no fuel.  Also, check the air delivery system, i.e.: your air filter, all its corresponding hoses to the air intake manifold, etc.  
When your TJ cranks, does it bog?  Meaning does it seem to struggle during cranking?  What are the temperatures like when you start your Jeep?  Temps have a lot to do with the time to start because your oil is a lot thicker and will not allow your internals to cranks as quickly as they need to.  Write back!

Thanks for the help Sean3090 but this one is not so easy. My Jeep has been to a few mechanics that cant find the problem. Cranking is fine and not labored at all. The problem started in the summer so temp makes no differance. It seems that when it doesn't want to start that there is no spark and the engine doesn't flood, it's like some parts of the electrical system are effected. Like I stated even the fuel gauge acts up when it wont start. I am thinking maybe its the crank sensor but would it be controlling so many things.
