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.
