check all connections on starter motor .solonoid,spray starter with wd 40 then try to start, remove n check spark plugs,if all good but still wont start then get an electrical tester on starter/solonoid,this should solve the problem but lots of other things could give you starting problems,worn teeth on starter,jammed starter piston,dirt in fuel tank,lack of battery power,lots more.
