I suggest reading the codes. The 3 ignition biggies dtc 16 , 41 , & 42 don't light the check engine light. But any of the 3 will cause a no spark condition.
You need to give us some history of your problem. Is this something that just started? Is the no spark condition been happening for a while? What testing have you done?
We have the 93 factory service manual in the 4th gen tech section to download. It has a driveability & emissions section with troubleshooting, explanations of the codes. Also an electrical section with wiring diagrams, component views, etc.
Did I mention you can read the codes on a 93 by shorting the dlc pins with a paperclip. Connect pins A & B together. You can find a pic of dlc at shoebox's site. It's # 53 in the electrical section.http://www.shbox.com
If you have opti problems , a $70 pc based oscilloscope is the tool of choice for testing low & high resolution opti signals.
