One night, about a month ago my car was running fine then all of a sudden wouldn't start unless i pressed the gas at the same time as turning the key, then the second i let off the gas it would cut out, no sputtering or anything, just straight cut out. After a few days it wouldnt start at all... I replaced the ignition coils, the cam and crank position sensor, as well as got a new battery... I then got it towed to a shop where they found out the fuel was flowing, had compression and spark but still wouldn't go, so they replaced the ECU... still brought up the same codes for the cam and crank sensor and still won't start... they seem to be stumped and i really dont want to keep throwing time and money at this thing. ANY BODY HAVE ANY SOLUTIONS!?!?!
