Need help diagnosing the following: Over the past 2-3 weeks my 98 TC van has begun making a whistling/whining noise that seems to come from the middle to rear of the vehicle and is more noticeable outside the vehcile, yet very audible inside the vehicle. The van starts and runs flawlessly as usual. No stalling, warning lights etc. I have a cheap OBD II Creader and it shows no error codes. The noise usually is not present first thing in the morning on my 10 minute drive to work. However, once the vehicle is warm the noise is there and sometimes seems to go away when the throttle is increased (even slightly), while at other times, it seems to go away when you let off of the throttle? When parking, the noise dies down about a second or two after the ignition is turned off (sort of like pressure bleeding off). According to the local dealer it may mean I need a new fuel pump (~$500). Before I do that, are there any other items I should check? Could a fuel filter problem cause these symptoms? Any other ideas? Thanks for any insights you can provide.
