It's something with the harness. Put the computer on another motor and fires right up. So both HP ECUs fire up one motor. I'll pull the harness to see what's going on.

My buddy had a similar problem with his Holley system. He has another unit on another LS engine without issues like you are describing. He felt there is a problem in the harness itself.

My buddy is Mas280 on here. PM him maybe he can give you some insight. He is slow at returning PM's.
