97 grand prix won't start

Alright I've got a head scratcher here. A 97 grandprix gt was moved one morning and in the middle of the move died and would not start back up. I have good fuel pressure and injector pulse, both cam and crank sensors check out, a bunch of O2 codes, atleast half a tank of fuel, new plugs and wires, ICM and coils are good, no broken grounds all are clean, new battery and good alternator, and good compression in all 6 cylinders. When I crank the engine over it'll stumble a bit like it want's to start once in a while. If I cover the MAF/TB opening it seems to damn near run but just won't. I'm at a loss and any help would be greatly appreciated.
 








LOL, yes.

Take a look at the fuses. If the heater circuits are all dead, you likely have a dead fuse that is keeping something from working or getting power.
 
Forgot to add that to the original post, but yes all fuses are good. That's why I'm at a loss. I've tried everything short of UIM/LIM.
 
Pull an O2 connector apart and check for power and ground. IIRC you should have power at pink and purple. There's definately two powers in that connector. If you don't see one, I'm thinking something ...somewhere isn't giving you power.

Try this.. Pull out a plug, is it wet with fuel?
