Engine Performance problem
2001 Ford Expedition V8 Two Wheel Drive Automatic 135900 miles
pcm is displaying codes P1131, P1151, P0174, and
P0174. The fuel pump is putting up 30 pounds,
(40 with vaccum hose off the regulator), but the fuel
rail is not holding pressure when the engine is shut off. Does this sound like a bad fuel regulator or a fuel pump problem?
have the same problem?
