I was looking over my engine after cam and header install It hasnt started.

Would this be the problem >>>> http://shbox.com/1/fp_reg.jpg

I didnt have the fuel pressure regulator hooked up at all..!

the one hose above the fuel pressure is plumed in with a group of wires that comes from over by the ECM

So you think It was the fuel pressure! that was causing all these problems?

Will the car run with this un-hooked?

The battery is dead now Ill have to wait for my buddie to come over.. alotta no starts in the past 4 days

 

It should run with that unhooked.It will be a small vacuum leak though.

 

you say it should run but should it Start?

Neither of those to vacuum lines where connected
