SOURCE: what is the code 12
The Code 12 on your Corolla it refers to a problem with the Rpm signal from the distributor, I recommend you to replace the distributor, make sure that is complete with the coil and igniter installed, you can save quite a bit of money by getting one from a salvage yard or an aftermarket unit from a local auto supply store !

Sounds like you may have an issue with the check valve on your in tank fuel pump. When these go bad, you have to crank several time to build up enough pressure in the fuel rail for engine start. With a good check valve, the fuel pressure will not bleed off and the pressure is retained for the next engine start.

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.
