Engine Trouble _ Will not start all the time

I am having problems getting my 90SC to start. I am thinking it might be the fuel filter/pump area(?) Do not think it is the starter. When I turn the ignition on it just seem to not get fuel(enough) to crank. Can anyone let me know what the problem might be before I turn it over to the Ford Mechs?

Does it crank and not start or does it not crank at all?
