Question about 1991 Chevrolet Cavalier
No gas, no spark, replaced ignition control module, coil packs, wires, plugs, ecm computer, map sensor,
This is an all too common problem with the Cavalier and other GM J-body cars. Usually it is because of the crankshaft position sensor or the harness going between it and the DIS (aka ignition module). Without the DIS seeing a signal from the crank sensor, it doesn't know when to trigger fuel and spark.
Sometimes this can also be caused by a faulty ignition switch. The switch will allow you to "crank" the car, but it doesn't make the proper connections for the ignition system, so the car never actually runs.
The previously indicated oil pressure switch could also be causing the problem, but if you hear your fuel pump run then it's OK.
Hopefully this helps. If not, your Cavalier is as messed up as mine and probably not worth fixing.

If you have a oil pressure GAUGE, replace the oil pressure switch, this controls the power to all engine functions including fuel pump, 1 way to check is turn engine over if you get no oil pressure then it will be sending unit or oil pump.
