after gm mas, went back stock, now car won't start

[mygsx2120]

I installed a blowthough setup and was having problems with it so I just put back on my stock stuff. Now my car won't run at all. Any ideas what the hell I could have messed up? I did drive it around for awhile not running right, trying to figure out the gm maft setup.

By the way, the car I am speaking of is not the one in my profile. It's a 93 AWD.

Even without the stock MAF connected, the car would start and drive in limp mode (pig rich conditions). Whats it doing?
