So the Jeep has been running fine I go inside the grocery store and I come back it won't start it just cranks and cranks but doesn't turn over. Luckily I was parked in front of auto parts store and the guy behind the counter was super nice he let me take a bunch of parts and try them out. Long story short I replaced every part behind the distributor and still would not get spark. checked the fuses double checked the fuses took apart the fuse panel cleaned all the contacts and still nothing. The store had only one new relay (i believe it is called a relay, located next to the battery) i tried it out on both positions and it still would not start and still no spark also i opened air intae above the tbi and did not see fuel. My friend took one of the relays off and stuck a pair of pliers and basically jumped the leads andi t fired right up. As it was running he pulls out the pliers and it dies we did that one more time and it fired right up. Bare in mind that all the original parts are back on. NEW PARTS! So just for the hell of it i ask him to p2ut in the old relay and it fired right up....... I am baffeled and electrical is not my strong suit please help. Also, i have only had one other issue like this in the last year, but i took the coil off and cleaned the contacts and it fired right up.
