Engine cranks but will not start

Good morning,

Fuel that is several years old is not good.

I would drop the tank, flush out all the old fuel and replace the fuel pump as well. Add fresh fuel when completed.

Change the fuel filter as well.

The pump should run for 2 seconds when the key is turned to the on position. Then it will turn on full when cranking.

Check the pressure when completed. You should have 9-13 pounds of pressure.
