Make sure your battery is ok and you are putting out enough volts and amps from the alternator to power up the coil packs at start up. Also check the crank case sensor...

battery is almost new. no check engine light and no codes. I have traced all the fuel lines from front to back and they all look fine as well. I have looked online and found this is a common problem with these cars, but nobody knows what the problem is
