I have a Heli CPYD25 TY2 S/N 230250L3040 that has the GM 3.0 engine with a no spark condition. The manual that comes with the truck is for a different engine so that is no help! I have power to the ignition coil but have no pulse reference. The unit does not have a traditional pick up coil in it. I have swapped out modules and cam sensor. Anyone have any ideas where to look to find the issues with this fine unit?
