Also try moving the throttle back and forth a bit while you are turning the key just in case your throttle positioning sensor is a little out of wack.
I have one that acts up occasionally when you turn the key it does nothing, then if I move the throttle it starts, happens maybe once a year. Also clean the ground cable end at the engine block,
The negative ends often get corrosion also small ground wires can corrode away inside the wire coating so continuity tests on any of those is a good idea or just run a jumper ground and see if that works then you know the problem.
