No spark at plug check coil wire. They did have problems burning coil wire.

U should really disable the fuel system by removing the fuse or relay, other wise ur dumping raw fuel into the cylinder that won't be burned. If the fuel starts to evaporate out of the cylinder and ur spark plug fires, you can start a fire and possibly lose your eyebrows...I've seen it happen- Safety first fuel, spark and compression are the things to check when the car won't start. if theres no spark, i agree with sg4356. try swapping some of them around and see if you get any spark with a different wire. its odd that no codes are being thrown, which leads me to believe the computer may be bad... if none of the coils spark when u switch them up, most likely the computer is at fault good luck
