Firebird wont start

[crazyeight]

First of all let me say hello to everyone.

My problem is that i cant get my firebird to start.
In the winter i have changed gaskets in the engine and now when i mounted everything back it wont start.

I have spark.
I changed all wires from battery.
I saw a video about top dead center and i have done that.
Fuel is coming to carb.

But the car wont start

Specs:

V8 5,0l
4 ports rochester carb
4 ports intake manifold

Year: 1987

Anyone have any suggestions?

Excuse my bad english

what gaskets did you change?

Did you check the connections to the alternator? I had a lot disconnected at once and a smaller wire that attached to the alternator found its way deep in the engine bay and when I went to crank it nothing happened. Can't remember if I had other power as well, but if you had a lot disco'd, I would just reconnect all your connections.
