As a general rule a car has to have three things to run.
1.fuel
2.air
3.fire
One of these three things is missing.Check if you have fire on all plugs and fuel to the carb.Air is usually not much of an issue unless you car is sealed in a air tight chamber or something.

You can take it to your local parts store. Most of them have an ignition module tester. If it winds up being a fuel pump I have heard it's better to go with the pump out of an 84 vette instead. Not sure why. Just what I've heard.

check the wires in the cap the go to the coil. i had one break about 6 months bad. if you have to ignition module checked have them test it 4 or 5 times to get it good and hot, that will let you know if its bad or not.

Check the obvious first...all the fuses including the ECM fuse. Try what someone suggested here...pour a little gas down each throttle body and see if it starts. If it starts its probably the fuel pump or fuel filter. If it doesn't its probably electrical...probably something to do with one of the modules (ther are 2) in the distributor or coil.
Only other thing that would shut off fuel supply would be a signal from the oil pressure sending unit. If pressure drops to zero its shuts off the fuel pump. Whats your oil pressure when cranking??

before you buy modules and other ignition parts make sure rotor spins when cranking motor . Have only seen it once but a timing gear that had
the fiber teeth torn off causes instant shutdown and bent valves . aftermath is no spark and no injector pulse not to mention motor that cranks weird

Dont forget the "prime pulse check"-remove air cleaner and turn key on and watch injectors for spray.With the coolant being cold you should get a good shot of fuel.Dont mean to sound like a stuck record but 50% of my "no start" problems with 1982s has been a fuel gauge that "lies".I always recommend putting a couple of gallons in to be sure because its difficult to see down into the tank with that little flapper and small opening.

I've got a new 84 fuel pump and everybody says you need an 85??

85 puts out about 40 psi. The 82-84 is the same and only puts out 9-13 psi. Crossfire motor needs constant fuel pressure between 9-13 to operate. The 85 pump guarantees enough flow. Car is more responsive. Idle is better.
