Make sure battery has a full charge. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure, also, check fuel injector pulse. Any applicable trouble codes?
You can try cycling the key on and off several times before you crank it, if that helps, I'd have to check fuel system.
Engine sensors , mass air flow , coolant temp , also fuel pressure and flow . Suggest you have a qualified repair shop look at it with scan data .

cylinder 1 is on passenger side, coils should be numbered, cylinder 4 is on drivers side

Not the IAC, or MAF, or 02
Does the Van Crank over?
Have you checked the IGN Relays? 1,2,and 3?
How did the Battery test out?
Anything below 11.9v battery is dead.
So I suggest that you do not throw any more parts and check the battery again.

That car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.
Testimonial: "the check the ground was a good suggestion, i will do that at my first opportunity"

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.
