The '83 and '84 FI system detects spark (at the coil primary) and completes the ground connection for the fuel pump relay. Your car has two relays -- both are the metal-cased style, mounted on the inside firewall, passenger side just above where the upper knee pad attaches to the firewall.
One relay is for the FI system, the other for the pumps. They're identical and can be interchganged. These relays are generally troublefree.
If you have no spark, the relay will NOT pull in. No spark means no fuel.
You can force the pumps to run by jumping fuse 5 to 7. If the car starts and runs this way, then you most likely do have trouble in the relay circuit.
Overall, those FI ecus are not known for trouble.
