Check the coils and PTU, also might want to check the ECU. Also, did you check all the ignition wires or just one?

If the engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark, the problem may be due to any of the following:

* A bad crankshaft position (CKP) sensor (on engines that do not have a distributor), or broken, loose or corroded wires from the sensor to the PCM.

* A bad ignition module (on engines that have a distributor or use an ignition module separate from the PCM)

* A bad pickup inside the distributor (on engines that have a distributor), a stripped distributor drive gear (common problem with plastic distributor drive gears), broken, loose or corroded wires from the pickup to the ignition module or PCM.

* A bad ignition coil (on engines that have a distributor and a single coil)
* A bad rotor or distributor cap (cracks or carbon tracks that are allowing the spark to short to ground)
