Onan 4000 ky no start

Don't know where to look next. This unit is about 10 yrs old total hours unknown. It has good fuel and flow ,spark and compression. Carb was gone through completely . New spark plug also. Does the control module tell the engine to start? It does appear to be a timing issues since it makes a "puffin" sound while cranking and cycling. If so can the problem be with the module? Thank you.
