1999 toyato tacoma prerunner 2.7L engine

Had to put on a new head gasket and got it all back together had a hard time getting gas in the fuel rail but got it started it ran great could turn off and it would start back up let sit overnight and it would not start i spray a little gas in the air intake and it started but after letting is sit overnight it wont started. Any ideal what could be wong?

 

I'd check the fuel pressure after it set over night.

 

is this something that happens after taking it apart it was running great before the head gasket blow i just want to make sure i didnt missed anything when putting it back together

 

if the pressure is gone would it be the fuel pump? Ive already change the presser switch
