like the topic say does anyone know what can cause fuel pressure to be sky high?
thanks

 

need more details? is the motor all original? do you have a FPR? return line pinched???? any mods... be specific...

 

no engine mods only intake+exhaust
z6 engine

i though it could be something wrong with fuel pump or fuel injectors but that doesnt make sence mostlikely if they were mulfunctioning it would cause a lower fuel pressure? correct me if im wrong

 

ok i did more research and it is probably the fuel regulator probably the valve is broken and its always letting in maximum fuel...? anyone had this problem before?
where could i get a fuel regulator for a good price

 

fuel.

lol

 

i just had this same problem with my car, after changing my FPR, fuel pump, injectors, fuel filter, fuel rail and some of my fuel lines it ended up being the little nut tyhat attaches the fuel line to the fuel rail. The nut was jammed up inside with washers

 

oh yeah and how is teh car running with the high fuel pressure?

 

You are such a idiot


I would think a valve or relay is facked

 

the car runs fine but there is black smoke when u rev it up and sometimes it smells
oh and it gets poor gas milage

 

upgraded fuel pump. if you have a 190lph or 255lph, your fp will rise and it can only be tuned out through the fuel maps in the ecu.

 

no the the fp is stock oem nobody touched it...

 

o2 sensor?
