1994 Jeep Laredo All Wheel Drive Automatic

i was wondering why my jeep never cranks up the first time.I had the alternator, the starter and the battery all checked out and they were fine. Could you tell me what 's wrong and/or how I could go about fixing this problem? Thanks for your time.

I would start with checking fuel pressure drop off. What that means is, when you shut the key, the fuel system should maintain pressure for several minutes and then drop to a point and stop. If you drop to 0psi very quickly, there is a leak in the system and that would cause the vehicle to be hard to start until the pressure builds.

Here is a How To for checking pressure and drop off. You will need a gauge to check it, but most parts stores will lend or rent the tool. Check if out and let me know what you find.
