I have a ONE SECOND TEST PROCEDURE STACKS. Jay that is why i have a spare known good DIZZY in my tool box. Remove the plug from the cars TIF plug it in to the test DIZZY key the ignition and spin the shaft with your fingers. (NOTE it does not have to be a dizzy of the same cylinders. For example yopu can use a 4 cylinder dizzy to check a 6 or 8 cylinder engine) If you have spark you know where the issue is. By the way Jay you do know that the DIZZY makes spark without the ECM even being hooked UP!!! So codes are a MOOT ISSUE!! THE TIF dizzy works void of the ECM. So if he is having ignition issues codes do not MATTER!! If he has a drivability issue he needs to pull codes that is a GIVEN.
