more on the Fog Horn

[Eric Billing <eric.billing@heimdall.sdrc.com>]

You may recall my post from a month ago... I reported a fog horn type sound from the rear of the car. Dealer thought it was the conveniance (power locking) package and replaced the pump. Guess what, that wasn't it.

As a reminder there is a cyclical (on for 8 seconds, off for 20) type of hum from the rear of the car on particularly warm days (80 F). On cooler days there is no sound. The sound usually is heard after shutting down (such as coming home from work), although has occurred when the car is under way.

Does this symptom sound familiar to anyone? Past discussions suggested the fuel pump as the culprit. Dealer says this may be so, but since the sound occurs when shut down, he's suspicious... By the way, where is the fuel pump... If I could put my ear to it while the noise is occurring, I might be able to confirm one way or another.
