The other posts were right on target. However, after checking the electrical connections for the fuel pump, check to make sure that you have a spark before going any further.

The relay to the fuel pump should have two modes, it should power the pump during cranking, and it should power the pump when there is a primary ignition pulse signal from the distributor. The second mode is designed that way so that it stops the fuel pump in the event of an accident, that is, if the engine stops running but the key is still on, and there is a break in the fuel system, it won't pump fuel all over the place. If you ever have a situation where the engine seems to start while you are cranking, but dies immediately when you stop cranking, and the fuse jumper described in the other post solves the problem, then you are on the trail to finding the problem with the fuel pump relay or circuit.
