2004 Malibu. Why won't it start?

SOURCE: my 1996 cavalier Z24 wont start

pull a wire and ground it via useing a screw driver at the end of the spark plug boot to check for spark / if their is no spark / ignition control module / there is also a crank shaft position sensor / located on the back side of the motor under the coil packs / pain to get to / also the nuetral safty switch / to check the neutral safty switch diconnect the big harnest at the neutral safty switch put a fuse tester to the yellow wire / have someone turn the key / with the tester grounded the light should come on / now we know the ignition switch has power going through it. if there is a no power at the yellow wire / bad ignition switch / does the car have a relay located at the top of the radiator core support (up by the radiator looking down drivers side)if it does not gm will install one for free / if there is / look for the purple wire coming out of the relay and Follow it down to the starter / reconnect the neutral safty swtch / touch the small S (the smallest screw) terminal on the starter soilenoid / have someone turn the key forward check the light / this will detemine if the relay is good / CAREFULL NOT to touch the big starter wire with the little one it will jump the starter / I HAVE THE SAME CAR / Hope this helps

change crank sensor? if so replace control module (ignition module)
