Fuel rail pressure

02-24-2004, 05:20 PM

Okay, key on, pressure rises steady to 41psi, then slowly drops back down, almost 10psi in 5 minutes. Engine running (idling), pressure remains at 39psi. Disconnect FPR vacuum hose, and it rises to 43PSI at idle. Any ideas?

Okay now, that's enough of that.

So.... 39PSI at idle w/FPR plugged in = too high? What should it be at?

Okay now, that's enough of that.
