Question No start E320, after K38 / ATA fix...

I have a '94 Cabriolet with the updated harness. I drove it on a very hot day and immediately noticed the blower not working so no AC. What's odd is the flat blower fuse is not broken. I drove it less than a mile and parked it for an hour to find it would not start. On one attempt it made a weird noise.

I used the wealth of information on this forum to direct wire the starter at X27 center pin thus pointing the problem to wiring, NSS, and K38/ATA. For those who aren't aware, turning the key to #2 position will make the car start, not just turning the starter. It got my car home.

At home I removed the ATA plugs and added the K38 jumper but still no start.

With the key turned to the right, I moved the shifter to both ends and heard a noise (air pump?) come on for only P & N but no start. I'm not sure what that means.

With key at #2. I have 12.15V to ground at the bottom holder of fuse #5 but only .75V at the top. What does it mean if I don't have 12V on top? I measure static 12.40V at the battery. If I remove the fuse the long black relay directly behind the fuse box buzzes. I pulled up the fuse holder but #5 appears to have many wires attached to that terminal underneath, mostly Violet and black.

I am planning on jumping the NSS after I remove the black panel under the dash and find the connector to test that switch.

I pulled codes 21 Purge switchover valve circuit open or circuit short & 26 Upshift Delay Faulty. I could not use my home made code reader for 8 & 14 because pin 16 only had.75V, not 12V and not enough to light up the LED.

What else am I missing?
