Check fuel pressure at fuel rail. This will tell you if it's good or not.

I have a similiar problem cranks no start funny thing is I drove to work my running lights would stay on and light knob was off is that a sign like error code bc no reads on computer check and my question when you check fuel pressure and you push the pins in remember car no start or dont run will gas still come out of the vaulve bc I pressed it in and nothing came out I checked relay got a new switch and a new icp sensor got it to fire 2twice with sensor off but when it ran by itself in park and if I hit break in and try to get out of park engine cuts of and dies had bad snowstorm day after this happened
