I think your problem is injectors not firing, and is linked to the Powertrain Control Module. Disconnect the battery for 30 minutes to reset the PCM. Reconnect the battery and try to start the car. If it still doesn't start, pull a spark plug and see if the tip of the plug is wet with fuel. If it is dry, then you are not getting fuel to the cylinders. If you have fuel pressure and spark, but noe fuel in the cylinders, it has to be computer related.

My 2004 chevy Malibu cranks but won't turn over

Typically a crank but no start condition is caused by the Crank Position Sensor. Fuel pump would be the second option

2011 Chevy Malibu lt. P0016 code. Replaced both cam sensor.and crank sensor still won't start

If you have the V6, they have a history of timing chain problems. The tensioner can go bad allowing the chain to rattle and jump time. This weill set the P0016 code since the cam and crank are not sync'ed and will result in a no-start condition.

2001 pontiac grand am se 2.4.car cranks ,but will not start.

The cam sensor is in the head near the throttle cables. The crank sensor is in the block near the oil filter. There aren't any sensors behind the balancer. If it is a problem with the security system the security light will be blinking. Does the vehicle start and die or just not crank or crank but not fire?
