I have a 2010 Hyundai accent. It overheated and blew the third cylinder. I too the head to get it repaired and replaced all gaskets, the starter, plugs and ignition coils. I also changed the oil. Now the car cranks but will not start. I can hear the fuel pump engage when I turn the key on but it will not start. I have tried everything I could think of. Could it be the crankshaft sensor?
