Question about 1993 Jeep Grand Cherokee
The first years of that body shape, like the 93 Grand Cherokee, had ecu computer problems. Next time it won't start, check to see if the check engine light does lights up on the dash, when you turn the ignition on, before cranking. If it does not, the fuel pump will not kick on, until that check engine light does come on. It's referred to as the delayed check engine light problem, on early to mid 90's Jeeps. If you find out that is indeed the problem, you can have the ecu computer repaired.
