New motor no fuel pressure? Help please

[92Rustang]

OK I just put my motor back in.New heads(windsorJr.),cam(e303),lifters(1.7),headers(s hortys),water pump, and all the little stuff. The motor spins fine, but will not fire. I have a autometer electric fuel pressure gauge that was working fine (3months old)it reads 0 fuel pressure. I cracked the fuel lines and found fuel ,but it just dripped out. It should have come rushing out correct?
I went over the wiring and plugs all looked ok. I checked the grounds three correct? Two on the back of the block and one in the front? I'm lost I can hear the fuel pump(155 3months old) kick on and there is fuel in the lines,but no pressure. Any body have any ideas. What should I check?
