I tried reinstalling the drivers and looked up how to disable checksum on Moates website. I made a separate bin file with checksum disabled. Also went back and checked continuity on all the ZIF solder connections including the 5 pins that get tied together. Still same issue.
Have you tried throwing a factory chip into the ZIF and seeing if it would still work? That should ensure that there were no problems introduced by installing the ZIF.

That was a great idea. The only factory chip I had was out of the 6 cyl computer but I gave it a shot and I have the same problem. I don't get it; according to my ohmeter all the connections have continuity where they should and are isolated where they should be.Originally Posted by fastacton
I have the same problem with one of the 7747 to 7427 adapter harnesses I built. I've triple checked everything and it seems fine, but just doesn't work right. It can be very frustrating.
