    If it runs with starter fluid, you are not getting fuel.

    Fuel pump relay, or the pump (can you hear the pump operate?)


    Edit: or, no fuel in tank.

    I'm not sure it is fair to say "it is for sure getting fuel" until you've checked the fuel pressure. If you haven't yet put a fuel pressure gauge on it, then that is the next step.

    published spec is 60-66 psi. When I had trouble with mine a few months ago, 45-50 appeared to be near the minimum needed to start.
