Did you check for spark? Is it getting gas at the fuel rail? If there is no spark then it could possibly be the crank position sensor, ignition module or coils but the coils do not all go bad at the same time.

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

Have u checked for vacuum leaks or poss leaking EGR valve? use carb spray around the upper intake manifold where it bolts to the lower manifold, spray vacuum lines where they are connected to the engine vacuum ports, the idle speed will change if u hit a leak, as far as the EGR valve goes see if it gets hot at idle, if it does it is leaking, if all checks ok replace the O2 sensor, but i suspect u will find a leak at the upper intake plenum.
