If the sparck fire has no fire, then check the coil module plug and clean with dust remover, then plug again and check if ther any fire from the coil conectors.

The point is if no fire never will come up, you will need to check this point to have fire.

Most likely the ignition coil or DIS System is not shorted out, but disabled. This vehicle is equipped with a passkey security system. What this system does is disable the spark to the engine if the computer thinks that the car is being tampered with. The problem can usually be traced to the ignition switch. This is where the passkey sensor is located. Usually replacing this sensor or full ignition switch will take care of the problem. On some occasions though they are few and far between a replacement key cut at the dealership may allow the system to operate correctly. Do keep in mind, this particular scenario only happens about 1 in every 25 situations. I really hope this information helps you. If not please notify me of the problem, I would appreciate the feedback. Good Luck!
