Get the fuel filter disconnected. driver side frame rail. u need a ford disconnect ring at the part store, then try the fuel pump with the key on. No guessing either fuel dumps out or it doesn't.
pumps vibrate and make hums but other electronics can too. Once the fuel poors out smell it if it's like turpentine linseed oil and not the distinct smell of fresh gasoline it won't start until it's heated up bad gas doesn't burn well but can run once up to operating temperature. Best to dump the gas and start with new.
If that doesn't work their is a pressure valve on the fuel rail once depressed fuel will shoot out another way of.verifying the pump is presuring the injectors.
Once running use a quality additive with high amounts of PEA like www.sfrcorp.com protecta fuel additive to clean up the varnish left behind from the bad gas
