Engine turns over but no start & fuel tank is full...
I have a 2002 malibu LS, v6, automatic... when I try to start the car, the engine will turn over, but won't start. The camshaft sensor is fine. Also, this may not be related, but the air conditioning cuts in and out.

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, check fuel pressure and fuel injector pulse. Go from there.
We can also check circuits for power windows.
Check for fuel, spark, and then compression. Fuel problems can be pump, pump relay, fuse, filter, line, etc. Spark problems can be distributor module, distributor, coil packs, power to distributor or coil packs, plug wires. Compression problems would be piston rings, piston walls, piston rods.
your car has a fuel level sensor on the fuel pump which is in the gas tank that is going bad this makes your engine light come on also makes your gas gauge read faulty, I think you can buy the fuel level sensor seperate from the fuel pump but i am not for sure my wifes car does the same thing i just havent got around to fixing it yet but when i do i will repost and et you know.
I think you may have answered your own question. I would check to see if the fuel pump is turning on when you turn the key on to the run position. You should hear a buzz sound coming from the gas tank. I would start there.
If car won;t start, but turns over it may be the anti theft system. Follow the directions in the manual-turn the key on and leave it for ten minutes or until the anti theft light goes out. Turn the ignition OFF and then restart the engine. If you continue to have problems with the anti theft system, disconnect the battery for 4 or 5 minutes and then reconnect. It seems to reset the system. Found this out after a mech. had worked on the system, disconnected the battery and told me it would be 400 to 500 to replace the module. Said no thanks and drove off to never have the problem again (so far!) 10,000 mile since.
