1998 Camry 4 CYL.

I replaced the timing belt, and water pump. The car got really hot afterwards so I turned it off and replaced the thermostat also. Now it will not start!

It will fire a bit when i crank it but not start..... almost like its not getting fuel. So i disconnected the line right above the filter to see if its pumping fuel and it started right up! Fuel shooting everywhere, i tighted the line back down and it died! what gives? I've tried disconnecting/connecting with the fuel cap on and off thinking maybe its a pressure thing... but can't get it to start with the line tightend. any help is appreciated! thanks!

I've checked camshaft position sensor, camshaft sensor and ignition coils.
