The car cranks, but does not start. ive checked the spark plug and it still fires up strongly and plus the engine light is on..
Hi there:DTC 1300 - Igniter Circuit Malfunction (No.1)
A DIS (Direct Ignition System) has been adopted. The DIS improves the ignition timing accuracy, reduces high-voltage loss, and enhances the overall reliability of the ignition system by eliminating the distributor. The DIS is a 2-cylinder simultaneous ignition system which ignites 2 cylinders simultaneously with one ignition coil. In the 2-cylinder simultaneous ignition system, each of the 2 spark plugs is connected to the end of the secondary winding. High voltage generated in the secondary winding is applied directly to the 2 spark plugs. In one of the spark plugs, the spark passes from the center electrode to the ground electrode and in the other plug the discharge is in the opposite direction, i.e. from ground to center electrodes.
The ECM determines ignition timing and outputs the ignition signals (IGT) for each cylinder. Based on IGT signals, the igniter controls the primary ignition signals (IGC) for all ignition coils. At the same time, the igniter also sends an ignition confirmation signal (IGF) as a fail-safe measure to the ECM.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

Do you happen to have a hacksaw blade? The thickness of the hacksaw blade is equal to the clearance of the
spark plug contacts. You can put the hacksaw blade flat
between the contacts, and make the necessary adjustment. Then, start your engine. Send in your e-mail
so we will know.

If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....

Simple thing to do is have your coils checked.. You should have spark if they are good.. If you still dont then disconnect battery at least 20 - 25 mins see if it resets ecm and alarm. May begin to work properly again..

If the code has cleared on its own then you need to disconnect the battery and re-connect it. This will clear the codes out of the memory. If you don't want to do this you can go to an auto parts strore and have them hook the little computer up to your car and they can clear out the code as well.
