Jeep Grand Cherokee Limited starts when I test for spark by grounding a spark plug cable to the engine. Thereafter the engine will start fine and run fine. In the morning it will not strt. Again, I test for spark by grounding a spark plug cable to the engine. The engine starts and I can drive it intermittenly all day long, starting with no problems. The next morning, again it will not start. I do the same process over and over, day after day. What is wrong?
