Anyone know Ford 351, FI no start ideas

Had a fuel pump problem on the Chevy suburban and by tapping on the bottom of the tank it would get it working again. It would stick, the other thing they told me is not to let the tank get below a 1/4 if possible. The gas around the fuel pump keeps it cool and when the tank gets to low it heats the pump up and leads to an earlier failure of the pump.

Another vote for fuel pump or possibly pump relay.

I've heard that said about every car/truck that has an electric pump. Which means all the manufacturers use a pump that must be submerged in fuel. Yet no manufacturer ever says keep the tank at least 1/4 full. I'm just not buying it. As long as the pump is pumping fuel it's probably being cooled by that fuel.
