your main relay switch may be bad. a quick way to check is turn key to on position and see if engine light goes off or stays on. if it stays on chances are your main relay needs to be replaced. I had that problem and replced it and have not had a problem since. The switch is located on the driver side kick panel. Just to the left of the fuses.
If you are getting no fuel, either the pump is weak and not pumping correctly or the fuel filer is clogged. Are you positive the pump is working? You should hear it run for a few seconds when you turn on the key and do not start the engine. Even if you hear it running it may be weak and need replacing. Change the fuel filter and see what you have then.

No, the engine will turn over it just will not start because it will be getting no fuel as the pump is not running.
Gas gauge stuck or not working & you are out of fuel. Filter plugged up. gas line broke or bent-check for a gas leak
If the starter is turning over on the 1989 Honda Civic but the engine is not getting gas, the problem is more likely the fuel pump than the injectors. Clogged injectors might cause difficult starts but a damaged fuel pump will cause the vehicle to receive no fuel at all.

Try checking the fuel pressure regulator that's what gives the engine gas and how much its hooked to a vacuum line.
If the injectors on a 1991 Honda Accord are working well than proceed to check the main relay and fuel filter. Replace the components if they are worn and check the engine with a diagnostic test.

Fuel pump not working / replace pump Also need to check fuel pump fuse and relay before replaceing the pump. It would help to know the year and engine size and what you are working on.
Just because you hear the pumps hum does not mean they are working. Also, where is the third pump? There should only be two, one in each tank. I am not aware of an F250 with a high pressure frame rail pump, how old is the truck? Have you pulled the fuel filter and checked for restriction? What happens when you pull the line off and turn the key on? Does fuel come out? When you say no fuel is getting to the engine, do you mean you have no fuel pressure, or the injectors aren't spraying anything? Could it be that fuel is getting to the fuel rail but the injectors are not firing? Could it be that you are getting some fuel pressure, but not enough fuel pressure? What if your fuel guage is wrong, and you have two empty fuel tanks? These are questions you need to answer to eliminate things down to your cause.
