So installed -8 feed and -6 return with AFPR and car wont start? Yes there is fuel in the rail i have pressure to the FPR says 60psi so I made some adjustments down to about 40ish psi and still no start. I have never had this issue before and I'm kinda at 🤯🤪😡. I pulled injectors and had them cleaned and they flow and are working like they should. So i put the back in and still not one injector is firing. I installed all stock lines and FPR and car started right up! I am so lost from this anyone ever had this kinda issues? If so what was the outcome..

 

a tune! is my guess. you are changing something in the fuel system.

 

are you also changing injectors?

 

uhhh,.,,,,

so you pull the stock fuel rail off. Put on a different fuel rail with a -8 feed, -6 return... with a regulator and fuel pressure is set to 40 psi... with the same injectors you had before and the car wont start?

you sure you just didnt flood it with the pressure up so high to begin with?

 

No nothing was flooded I pulled spark plugs and had my wife turn the car over and not one injector was firing. I turned the fuel pressure down and still nothing.. I took injectors off cleaned them tested them and everything was good so put everything back and still nothing..

I go back and install all my stock stuff and car fired right up
And yes this is all with the same injectors.

 

Nope same injectors

 

Did you happen to disconnect anything electrical to relieve fuel pressure?

 

Did you pull any grounds off? Double check you don't have a grounding issue.

 

Nothing is different only thing that was unbolted was fuel rail no grounds or anything electrical was removed.

 

this might be a dumb question but are you sure fuel is flowing through the rail and getting to the injectors?
