The barrel is not timed properly to the switch.
If the car turns over, gets gas and just will not start try the ignition module. CAR TURNS OVER
I had this same problem when i bought my cavalier. I had the ignition lock\key part changed and I changed the ignition switch myself and it worked fine. Now I have yet another problem.
Something is keeping power to the ignition coil. You need a wiring schematic and trace the wiring.
Replace the ignition coil.
is there spark to the plugs? is there fuel to the injectors? timing correct? check these things in order and deal with each one to find the answer. too many variables at this point, need to narrow it down
it sounds like you have a faulty ignition barrel
six
all cars start of with matching locks/ignition and key so the ignition or locks must have been changed
possible crook ign. switch contacts or crook starter motor.
change the crank position sensor
I've replaced ignition switch, and starter solenoid, checked fuses, and battery, but I don't seem to be getting any electrical through to start the engine. I can jump everything and get the engine to turn over but not start.
stealing is against god's ten commandments and it hurts people.
Hot wire it. Take the wires out from under the ignition barrel and splice 'em together
The key needs to be coded to the new barrel, or swap the immobalizer ring from the old barrel to the new one(if using the old keys)

check your distributor ignition module and go test it...
Turn ignition on but dont start the car, then press and hold the trip meter reset button down for ten serconds or until it beeps
