Engine size (3.1L M vin, pushrod motor)

I have a 99 Olds Cutlass that had a lower intake manifold gasket leak. Coolant was coming out of the side of the engine - but there wasn't any in the oil. Other than that it ran strong. I bought the improved LIM Gasket kit and with the Chilton guide online - was able to compelte the job with little trouble. I did have the rocker bolt strip out on me - but I repaired that with adding a heli coil. On tear-down, I missed the o-ring off the fuel rail - and did not notice it upon reassembly either. And, of course, when I tried to start it - fuel sprayed everywhere. So, I replaced the o-ring and rechecked for fuel leaks.
I tried to start it again - and it turns over but does not start. I did not hear any clunking or unhealthy noises. So, I pulled the front rocker cover to inspect that - and nothing is broken or bent. I don't have a fuel pressure guage - but when I pushed on the fuel rail port - fuel did come out (and the dash fuel guage reads that it still has about a 1/4 tank). It looks like all electrical connections are good. All vaccume hoses seem to be connected to all the right places. The battery did have a low charge - but the terminals are clean and should have plenty enough to do it's job. Plugs/wires are used- but in good shape (maybe old) and running to their proper locations. No dipping has been noticed - so nothing seems to be leaking. I'm stumped on what action to take next to get it running - any suggestions or ideas that I should invesigate?

You need to find out whats missing. Spark of fuel? Spray some starting fluid in the throttle body & see if it starts. Double check the connectors to the module under the coil pack & make sure you didn't bent any pins also make sure the injector harness by the alt is tight. I've seen some of those pump down lifters on reassembly & you just have to crank it for a while to pump them back up.....
Hopefully you torqued the rocker bolts & manifold bolts. If the rocker bolts are overtorque they can pull the threads out...
