motor trouble

Got a Yamaha 115 that is giving trouble....it won't fire. Been playing up a bit over a while now but has finally stpped firing. Not a fuel feed problem to the filter on the engine but was wondering if it could be the fuel pump or electrics?  Any ideas?

plenty of fuel getting through...even tested with a hand tank and the line is primed right up. Will check for spark but the plugs are fancy looking buggers and hard to get to

will it fire if you prime the fuel up with the priming bulb while trying to start it,

is the fuel filter blocked,

check all hose clamps on fuel lines to ensure there not sucking air,

check fuel quality (make sure theres no water in it),

a quick way to check if you have a fuel system prob is to disconect fuel supply and spray start ya bastard down air intake while cranking if runs this is a good indercation of a fuel/fuel system problem, check spark plugs arent wet/fouled first

like said above does it have a good blue spark check at all cylinders,

check some simple things like this before replacing parts.
