I have a 2001 Mercury 115 4 stroke fuel injected outboard that won't fire. Checked spark plugs - getting spark. Checked fuel lines, no leaking, bulb is hard. Spayed ether and engine fires but cuts off. Checked fuel to fuel pump and check all fuses. Boat ran great 2 weeks ago and I started in my drive way last Wednesday. Any suggestions??

. Ensure battery is fully charged.
. Clean battery terminals and cable connections. Ensure connections are tight.
. Check fuses with a test light or multi-meter--not visually.
. Remove spark plugs and check each cylinder's compression.
. Replace spark plugs with the exact ones that came in the engine, if the compression is fine.
. Check condition of spark plug wires.
. Check that the fuel pump runs, when the ignition switch is turned to ON.
. Replace fuel filter.
