Check the plugs for spark, pull one out and lay it on a metal part with the wire attached,, crank it over and see if it sparks, if yes, then squirt some fuel in the throttle and see if it fires, narrow it down to something. Check the oil, the electrical sensor in the header is an oxygen sensor, it will not effect the engine, If you don't have a spark, pull the coil pack off the old engine and bolt it on the new one. Check it out.
