Yukon Denali 07 fuel pressure

[egxlover]

Hello ,

recently purchased used Denali 07 , and i love it ! , noticed the mileage was horrible even for a a Denali though , i started checking things and found the pressure on the fuel rail test point on idle is 95 PSI , engine off and pump on is only 50 , i was wondering if anyone has the specs for the engine running fuel pressure , if it is high what could be causing it? as far as i gathered from searching there is no fuel pressure regulator on my fuel system to check , can a bad pump module cause high pressure ?

i have been having difficulty finding information regarding the normal pressure range on the return less fuel system i have

Thanks for taking the time to give your input .

can some with the same engine just pitch in and tell me his idle fuel pressure?

I believe it is 50-60 psi at idle. I got a fuel pressure gauge on mine and will look at it when i get home.
