Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

Chech the ground on the pump from wire harness from tank....they get old and lose the capacity to ground ....also check for power at the tank with a circuit tester....if no power...you have wiring issues...

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.
1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..
2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)
