ok so i have a 97 xj. most of the time it starts fine......every once in a while (usually when it has not been run in a day or so) it wont start. i keep getting starded everywhere. usually after while of messing with it, it starts up. i had it towed to a shop but when it got there it started right up so they said they couldnt find what was wrong unless it wasnt starting. now it wont start and i need help with what to look for. it seems like spark or fuel because it sounds like it wants to start but just wont turn over.......please help

 

check your fuel pressure with a gauge make sure the pump is running and check your coil and

 

X 2, sounds like fuel pump heading south on you.
