Your fuel injectors need a steady supply of electricity, so when your alternator belt broke, they weren't getting enough juice to run properly, therefore your engine died.
I would make sure that your battery is fully charged, the new belt is properly tensioned ( new belts often 'stretch' and this will undercharge your battery), and that the Alternator is working properly. This can also set a computer 'trouble code' causing the check engine light to come on. Have your mechanic 'clear' the computer codes and if it returns, there is a new (and probably unrelated) problem.
Of course, I would check the obvious first, did a plug wire come loose?, clogged air or fuel filter, need a tune up, etc.

Sounds like you have an air to fuel mixture problem, have you put a scan tool on it, being a gm i suspect it may be the mass air flow sensor/map. Pull the codes to see why you are dumping fuel

Car not firing

Most likely the valves were bent.
When you attempt to start the motor does it turns over a bit fast and will not sound quit right - Not even attempt to spark up or fire up.
Check engine cylinder compression. The valves were bent when the belt broke.
you will
1. check compression (and when it fails)
2. decide to have the head checked and if possible rebuilt (use new head bolts)
3. Look for and buy a low milage used motor
4. Look for a rebuilt head

double check your firing order and make sure all wires and hoses are plugged in good. when you pulled the push rods out did you make sure they went back exactly where they came out because there are 2 different lengths.
