Hello...I have a Yale GLCO50 that I removed the engine from and took to a rebuilder for a customer...I picked up the engine when it was done and installed and hooked up but have no spark. All fuses are good....appears everything is hooked up right. But no spark. There is power to the pickup coil red wire...Do these units need special programing to recalibrate once the distributor has been removed? Can anyone help me through the process of testing to find out why there is no spark?

Thanks
