02 cranks but will not start

Hello everyone ,i have a 2002 GRAND AM se 3.4 The engine turns over fine but will not start or even fire. Any ideas as to what I should look for. I already tried turning the key on and leaving it for 10-12 mins 3 times and no luck. thanks for any advice.

Have you checked for spark and or fuel???

yes test for spark, test fuel pressure, and use something like long socket extension to touch one of the injectors while someone is cranking, if theft system is OK. you should feel injector ticking which means pcm is comanding injectors to put fuel into cylinders. If not then the theft system has disabled the injectors. If you don't get spark, test ckp sensor at the icm connector (purple and yellow wires) you should get about 200 mV of AC, if that checks OK. then remove coils use test light when you remove coils you will see two male terminals sticking out of the ICM, connect test light across each of the terminals while someone is cranking you should see light flicker for each 3 coils. If all 3 flicker when engine is cranked icm is OK.
