03 honda rancher not firing?

just got this bike and i cant get it to fire. dash lights come on and cant get a neutral light to come on, the gear says "--" so im thinkin this is why it wont fire. when i unplug the 22p connector the neutral light comes on but no fire. bike is definetly in neutral and rolls fine and turns over fine, any help would be much appreciated.

Welcome to the forums. Might be a bad gear position switch. The service manual will show you how to test it.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Find the light green/red wire going to the gear position switch and temporarily ground the wire and see if the neutral light will come on. It should come on if you're getting power to the neutral light because the light green/red wire just grounds the circuit when you're in neutral.

It's strange that the neutral light won't come on if the gear position switch is good.

thanks , i tryed to ground the green/red wire allready and didnt work. well i officially solved the mystery, well not all the way but heres what i did, i noticed i didnt have 9 volts or whatever at the icm black/white wire so i ran a strait wire from the battery and wallakabing, everything works perfect, i hear a click in the ecm and the electric shift works perfect. must be a bad connection somewhere but i checked evrything i could possibly think of. so it will be ridable atleast ,thanks all.

i would say your not getting power from your battery to your ignition switch..back to your ecm...start at the battery..and work your way to your ignition switch..then from there..back into your wiring harness.
