My fuel pump is whining kind of loud ...even with a full tank. Sometimes when I shut off the engine I hear the pump still going for a few seconds...up to five...and the pitch of the pump changes. Sometimes at a stoplight the pitch changes too...kind of like it goes into high gear for a few seconds and then quiets back down. I am also experiencing the "bucking" problem early C4s had with the car acting like it's starved for gas when getting on it from a stop and turning left hard. It does it now when I'm still at 1/2 tank. This is only the 3rd time I remember this happening and it has always been when I turn left hard from a dead stop. Yes, the filters have been replaced.
All these symptoms make me think it's time to change the fuel pump. I know someone gave me the part number for the B2k pump used...does someone out there still have that number for the '87 TT? Do my symptoms sound like the pump is going out? Does your pump normally maintain a solid tone to its whine or does it vary in pitch?
1 last question. I have a friend who is fairly good with shop work like this and he's a service manager for Chrysler although he's a Chevy guy from way back. Is this a job that we could pull off ourselves or is it best left to someone who's done it before? I hear it's easy to screw up the fuel guage sensor. Opinions?
