Locate your vehicle's computer connector (ALDL), most are on the lower driver's side. In some vehicles you might need to look around a little, on the passenger's side, and around the center console under a plastic cover. For more information, check your owner's manual. This device gathers information that was stored in your carsECM. This information ortrouble code can inform you the system or sensor that is malfunctioning. Look up the code in our diagnostic trouble code chart. After repairs have been made use the code scanner to clear trouble codes and recheck system.
B. Testing Fuel Pressure. Test for proper fuel pressure with a fuel pressure gauge. Connect the gauge to the test port on the fuel rail. Fuel pressure reading's very depending on the system your in our vehicle, but most throttle body injection cars (TBI) are between 13 psi and 17 psi. and most (DPI) direct port injection systems are between 40 psi and 55 psi. To find out your vehicle system fuel pressure consult arepair manual. If little fuel pressure is present the fuel pump needs to be replaced.
C. Test for Weak Ignition Spark. A weak ignition system can be a sign of a failing ignition component. Remove spark plug wire and insert an extra spark plug into end of wire, attach spark plug to engine ground then crank engine. You should observe blue spark between spark plug gap. If a yellow spark is observed, your ignition coil is weak and needs to be replaced. If your spark is not consistent you may need a ignition module.
D. Inspect the Main ECM Relay. If the ECM relay fails it will shut down the engine management system. This relay carries high amperage and is prone to failure. To test install new relay then test drive to recheck symptoms.
E. Testing the Ignition Switch. This test requires a electronic test light. When vehicle dies test the power side (+) of your ignition coil with the key on, the test light should illuminate. If your test light is not lighting suspect your ignition switch or ignition relay. To trouble shoot this condition you will needwiring schematic for your car.

Check all of your fuses, sometimes a short will trip a fuse that controls the spark to the engine, and it will shut off an not start all of the sudden. Im not sure what one, but check them all and replace them if they are blown. Other than that it could be the ignition coil or a bad distributor?

1984 ,its a classic ,is it carb or fuel injection?? should imagine its carb for that age so most likely a manual pump driven from the engine ,if following the fuel line back you should find it .If no manual pump on engine then an external electric fuel pump mounted ?? possibly at back by fuel tank ,if you keep following fuel line and still cant find it then look at how many wires on sender unit in fuel tank .Four wires means its inside fuel tank two of these wires will be thiucker than the other two
