I have an STX-12F we ran it fine about 3 weeks ago out on the lake all day it was great we took it out for memorial day and it wouldnt start.. it only has 23hours on it... heres what ive done:

checked spark on all cylinders its good
it turns over fine and has a new battery
we took the fuel line off the filter and tried to see if the pump was sending fuel got nothing... im hoping my pump is not bad... i checked power using a test light to the fuel pump power conector grounded it to the block and had power... not sure what else i can check... any ideas?

it will fire if i spray starter fluid into the cylinder... any way to check the pump?

seized fuel pump

You may want to quit using gas that has ethanal in it. It absorbed moister, then evorates over time, leaving water behind in the tank, fuel pump, etc.
