hey guys im new here, bought a 91 yj and it will not throw any spark, i put in a new distributor, coil, crank sensor, ecm and spark plugs. still will not throw spark. the gas was low when it last started, i felt a sputter in the engine that felt like spark plugs were bad. ever since it was low on gas, and i changed the spark plugs it will not start, i have taken it to a shop, they tested everything on a bench, 100% working, put it back in and it will not throw any spark. please help me!!!
