2002 Grand Am cranks but wont turn over

The car will crank and crank but will not turn over. I am at a loss here.
Things I have checked or replaced.
-Ignition system components
~Spark plugs, wire boots, Ignition coil, Ignition control module, ignition switch, ignition cylinder, and I did the security relearn process 4x. The security light is NOT flashing when attempting to start, but does come on during the initial turn, (therefore I know the light works, but it shuts off). I also replaced the Crank Sensor and the MAP sensor
I pulled the coil off and grounded the coil pack and the plugs and I am getting bright blue spark on each plug.
-Fuel system
~checked for fuel pump voltage, fuel pump is working.
~Tested fuel pressure, sitting at 55 PSI
~tested injector power using noid lights, all injectors are pulsating.
I also removed the valve cover to check to see if the timing chain was snapped, but it was was not and moved smoothly while cranking.
The car will not start with starting fluid either.
I am doing a compression test later today, will update as I advance on ideas.

Welcome to AF!!

You didn't say what engine you have but if the engine has a cam position sensor you may want to replace that. If not given all the parts you have changed and checked the only thing left in question is the PCM or computer what ever you wish to call it. Given the fact that you have checked everything but compression if that test comes back acceptable then the computer is the only thing that is left. If you decide to change it try to find one at a wrecking yard. They will guarantee them and if it is bad they will replace it. If you purchase one from a parts store once you install it they will not take it back.

Good Luck!
