Re: 2001 Trooper starting problem

Well, I would have to say that the fuel pressure regulator is definitely not supposed to have fuel in the vacuum line, so the diaphragm or whatever inside is definitely not right. I know some GM vehicles have exhibited the same failure, and it is difficult to diagnose unless you have some experience. This extra fuel has been known to compromise the catalytic converters due to the over rich fuel mixture, so fixing it will have far greater benefits.
Sorry I don't know how it attaches, but Amigo gave a good illustration, so hopefully that will help.
Good luck
