92 Sport, 4wd, 4.0L
On Monday, a high pitched squeal began emenating from the rear of the vehicle, somewhere in the vacinity of the gas tank. It sounds like the brief sound hear when the fuel pump engages when you first turn the key, only it is continuous and not as loud.
My son drove the truck Monday and Tuesday with no problems. On Tuesday evening, he lost power while under steady acceleartion on a flat surface. It sputtered for a minute and then came right back.
I did the search thing and found three schools of thought:
1. It is the fuel pump and it is going out, so I had better replace it.
2. It is the fuel pump and all of them make this noise and I have been driving mine for years, so don't worry about it.
3. It's got nothing to do with the fuel pump, it is somewhere else in the fuel system. Most probably _________ (insert one: relay, ballester, hose, clamp, filter, intake, TPS, CPS, NSS, ABC, EIEIO)
I tend to lean toward 1, since it hasn't been making the noise and the truck did sputter and I always follow Ocam's adage - entities should not be multiplied beyond necessity.
I don't doubt that there are Jeeps out there that whine all the time, but this one has not been doing that...
What is the general opinion - should I go ahead and replace the fuel pump or let it ride until it doesn't?
