I wish you all the luck, don't take me wrong, if you can fix this like this great, but it is still an expensive gamble.

I spoke to a mechanic friend of mine, and he told me after I have the engine warmed up to shut it down, and pull the vac line. Well I'm assuming that the small black rubber line on the top of it is the Vac line (it's 0 degrees outside with negative windchill, didn't take the time to follow the line to see where it leads).

Well when I pulled the line fuel came out. He said if fuel leaked out, the regulator was bad and that I should replace it. But with the amount of fuel that came out I just wanted to make sure that this is actually the vac line and not the fuel line. Because like you said, I don't want to replace something that I'm not sure is bad. All of my engine experience is on small engines, not on vehicles.



***EDIT***

I spoke to my friend and he confirmed that it was indeed the vac. line, so I guess I'll be replacing it.

Man, this did do the trick for me too! Thanks everyone that post here. A dealler would have charged me over $200 to diagnose and fix....

I dont know were I would be without this place.

Also I wanted to note that there are 2 versions of this fuel pressure regulators. 99-00 use version 1 and 01-up use version 2. Napa was the only place that sold both. Orileys, autozone and advanced only had version 2. Version 2 made my truck run funny and the regulator made a vibration when installed. Just an fyi.

Also with version 2 you will get horrible gass millage. I went ahead and purchased the one from the dealer after making the mistake of buying the one from Advanced Auto Parts.

I have had the same problem with the truck not starting properly. I did pull the vacume line off the regulator and if fuel does come out, then the regulator is bad. That is how my cousin, who works at the dealer, check the regulator. However, after replacing that a month ago, I am back to it not starting properly. It is not the regulator this time and I just replaced the fuel filter about 3 months ago. I am going to check the fuel pressure this weekend. The truck only has 84 K on it. Any other suggestions?
