no start 97

hey folks, got a 97 lumina that ran,then proceeded to completely die. what i got is plenty of fuel to the injector rail, lots of spark. when turned over no start as if the injectors are not getting juice. typical lumina,previous owner let the intake leak so bad that it filled everything with slurp. sooo am i looking at this all wrong thinking bad cam sensor or maybe something else controls the injectors thanks

You have to gauge check the pressure at the rail...it may seem strong, but needs around 35+ psi I think or the injectors will not open...
