Bill,
Did you try a reset 18 again to see if it will work first? I would try this first as you didn't do it right in the video and is worth a try. It will also get you familiar with doing other programming such as horn in neutral which I do on every PS! engine since I use a Z-4000 also.
1. With the handles in the off position, press PROGRAM
2. Bring it up to 18
3. Press SELECT
4. Listen for the 3 clinks and 3 clanks
5. Press SELECT until you hear the garbled bell sound
6. Then press PROGRAM to lock in the reset
It should now be ready to run next time you want to run the engine. The engine will come up in reset as usual when first powered up. Wait a few seconds for the engine to warm up and then move the throttle to off slowly and then back up and your engine should move forward if it just needed to be reset to factory defaults.
