OK, I can start the one engine the other will not make a peep.. no ticking, no beeping.. nothing.. last year this would happen from time to time that I would push the starter and nothing and then push push and push and then there would be a connection and it would start.. I thought it might be in the little button so I switched them around and it start the good motor off the bat... still nothing in the bad motor with the previously good buttion... where to next?
