I don't know what testing you've done? How long since a tune-up? Any applicable trouble codes? To check codes yourself, at the least, you need an obd2 code reader.
In the diagram, see the pink wire at ignition coil, that is primary voltage to coil, with key on, use a test lite and see if there is voltage? If no voltage, that circuit is fuse protected, I believe ecm 1 fuse, under hood fuse block. You need to do some testing and tell us what you find?

Where did you check for spark? Unplug the coil wire from the distributer cap and check there by placing the end of the wire near something like a ground wire or head bolt while cranking the engine. Don't hold it in your hand. If you have spark comming from the coil wire but not from the cylinder wires then I agree with stevevpb. Very possibly the cap and rotor. A word of advice. If you decide to replace the cap and rotor and/or possibly the iginition wire set as well, use only OEM parts. Yes they are more expensive but many aftermarket ignition parts wind up costing you a lot more in the long run. I've learned that the hard way. An OEM cap will probably run you about 50 bucks; rotor, 20 bucks; wire set, 150 bucks. What a rip but hey, it is what it is.

check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor
SOURCE: No spark
check the coil pack to see if you have any spark coming from it and also here is a website if you need any GM parts www.schramauto.com or call them at 1-800-292-1032

This sounds like a classic fuel system problem. Manually check your 1 & 3 plugs to prove /disprove the code. If they're OK, which I'll bet they are, check the fuel pump. If it tests good then you have a fouled gas tank, I'll bet. Especially if you live in the Northwest. If you let it sit with low fuel, the extra air space lets condensation form, causing rust and moisture in your gas. Usually changing the fuel filter will give you some temporory improvement if this is the problem. If it didn't then it could be your air intake not delivering enough flow to give it the proper fuel/air ratio. When's the last time you changed the air filter?

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.
