We have a Plymouth Voyager '94 6 cylinder 3.0L with fuel injection. It has 104K miles on it, and has been well maintained.
It had a whine noise in the rear of the car that developed one long trip. It would whine like a high rev electric motor when you just turned the ignition switch one click (this did not start the engine). The whine would persist as long as you drove the car.
From reading on these group pages this seemed to indicate the electric fuel pump was bad. The pump is located in the gas tank . We took it to a mechanic and he confirmed the diagnosis but he did not have time to repair it till the weekend. So we jacked the car up in the rear and we replaced it ourselves with a NAPA fuel pump part... It fit OK and no leaks. Then I started to replace the fuel filter.
When I looked at the fuel filter cannister under the right middle undercarriage. It was shiny new. We looked at a previous repair bill done by our local mechanic a couple months ago and they replaced this fuel filter. So I did not bother with replacing it.
So we start the car up and it runs....BUT there is still a whining noise coming from the rear...which I guess suggests the fuel pump is under strain from something.
- Any ideas what to look at next? Junk clogging the lines?
- Is there a second fuel filter in the car? Perhaps the fuel filter the mechanic put in was defective (or backwards).
Thanks,
Nate
