Possibly. I'm believe that your '84 has the white 1"x2"x2" relay box with the Fuel Pump/Fuel Injection relay just above your computer in the passenger side right kick panel. Of the two solenoids in that relay box, I believe one of them should turn on for several seconds when you turn the key to position 2, but the other one does not energize until you start cranking the engine. Swap the relay with your spare and confirm that it's working properly. ($4 at a salvage yard)
As for Air Mass Meters, I was pretty sure that when they failed, you would experience a no-start condition. However, I just pulled a 007 Air Mass Meter from a friends 740 Turbo that had failed (missing Platinum wire), and this car was driveable. -However, it was driveable but running in full-rich mode and consequently melted the ceramic core in his catalytic converter. Thus, an AMM could fail in such a way as to allow or not allow the car to start. Personally, I'd pull the unit, look through it to observe the integrity of the Platinum wire, and then swap it with the spare/backup that I keep in the trunk ($35 at the local U-Pull-It salvage yard).

Make sure that it's positioned properly. If it has gotten any amount of slack in it and the tensioner wasn't adjusted, it can hop one or more teeth and thus prevent the car from starting.
As a next step, I would probably spray some Ether or Starter Fluid in throttle body and try and crank the car. Try and determine if it's a no-spark issue or fuel deliverly issue. If you can get the engine to cough a few times while cranking, then you're getting spark and should look further into fuel issues (like prepumps and pumps, hoses, stuck drainback valves, filter plugged with debris, etc). If the car does not cough at all, and you pull a spark plug and there isn't any spark, then check the ignition system (hall effect sensor in distributor, ignition coil, cap, rotor, ignition coil wire, 25A fuse connections, etc). Also make sure you've got more than 3/4 of a tank of gas in the car, just to rule out some of the possible pre-pump & tube issues.
Lastly, try to rule out vacuum leaks. If you've got a big crack in the accordian tube, you could be sucking enough air in to be outside the limits of a "combustable" mixture.
God bless,
