The first thing I would check is the supply line to the fuel pump from the gas tank. You could have a clogged fuel pick up sock.

Pop off the distributor cap and have someone crank the engine over and see if the rotor is spining?I suspect the rotor isnt turning and something has happened with the timing chain. That would explain why the fuel pump is inop.
