I also have 3.3v at pins 5-8.Make sure you have 3.3V at pins 1 and 3, pins 13 and 14 voltage depending on the RPM pots position (0V to 3.3V), and that all the other pins are either floating or at 0V. If this is not the case then there is a problem with the board.
Could anyone point me in the right direction?
This is my first megasquirt project. I searched the forum and didn't see any other posts with a similar issue.
Thanks!
