Well I have mainly two questions.

Does the VATS system from a '93 z28 control spark and fuel, or just fuel?

I used a VATS bypass module, do I need the 30 hz version for a '93, or do I need the 50 hz version?

Basically, after my swap into my '79, I went to start and no spark. I checked the coil, and it tested good via ohmmeter. I have no spark between the coil and distributor. Also, I'm getting code 46, which is for Passkey II. Anybody have any suggestions? I have the 50 hz version, do I need the 30 hz version?
