Try this. Take a hair dryer and warm up the ehc before you try to start it. Be gentle and dont warm the unit not toast it.Turns over good, and has a deka battery in it. It kills the battery trying to start it in cold weather. Fires right up when warm. It is frustrating.
Turn the key on and look at the ignition module when you select the run button. You should see a red light come on indicating it is getting power from the EHC. If you don't get the light do as Jersey Big Mike suggested and check it again. No light means no ignition. If you get the light my next suggestion is to give one squirt of throttle , hit start and wait until the bike is cranking then raise the enricher (not choke) 1/4 to 1/2 way.compression releases work, Turns over good until it kills the battery. Choke works and has one level
