Toyota Repair: 94 Celica GT has no ignition spark, digit code number, engine cranks

Question
My daughter's 94 Celica died on her way to college. The engine cranks fine with starter, but will not start. I pulled  spark plug wires and there is no spark to any cylinder. The engine is a 1.8l 4 cyl. with a distributor. What I have checked so far: Timing belt is ok, cams are turning. I checked all the fuses I could locate. I pulled the cover off the distributor and checked the air gap at pick up coil (OK). I would appreciate any pointers the members of this site could provide. The parts manager at the dealership told me that an expensive part called an Ignitor could be bad. Is there a test I could do to verify the ignitor is bad. Thanks..Mike

Answer
It is possible that the igniter is the problem but the signal generator in the distributor is a more likely cause, this will result in a loss of spark confirmation signal to the computer.
The first I would do is to check for diagnostic codes, on this model year you can do this yourself.
Locate the diagnostic check connector under the hood and open the cover, locate the terminals TE1 and E1 and put a jumper wire between them, turn the key on, the check engine light will start to blink, if there are no codes it will just blink with no pattern, if there are codes it will blink a two digit code number, for example a code 12 would be one blink followed by two with a short pause and then will either repeat or show another code, let me know if there are any codes.
