Fuel pump??

[Earthworm]

What are the symptoms of a failing fuel pump?

My car is emitting a squealing noise coming from the back of the car. Has happened right after starting but goes away after a few seconds and doesn't come back. 3 or 4 occurances in the last week or so. The car does not have to be moving.

The sound is not unlike that of a dying computer fan.

Also would different fuel (ethanol blend) cause this problem?

[wawazat??]

but if you determine the pump is failing, I have one.

Good luck,
Todd

Poor diagnosis on my part!

Turns out nothing is wrong with the fuel pump.

I found out later that the noise WAS ONLY when I was moving...not like I previously mentioned.

At first I thought a rock got into my brakes but the noise didn't really change when I applied the brakes/e-brake.

Took the wheel off and found that one brake bad had worn almost to the metal! It was the screecher causing the noise plus my brakes were dragging.

Long story short, I replaced the rear pads with OEM's w/shims like it's supposed to have. No more noise. Tire wore a bit unevenly as well. (getting AVS db S2's anyway)

I recommend everyone check their calipers at least once a year and clean/lubricate the guide pins.

Here's the brakes I took off...
(note the one bad pad)

Here's the brakes I put on...
(look at all the shims I was missing)

Here's the tire that I'm sure was damaged as a result of the brakes...

David,

I'm sure not a mechanic, but why do you think it was the brakes? I've never heard of brakes causing weird tire wear. Shocks/struts, or alignment, or bad tire (out of round or ?), out of balance, poor inflation, etc. but not brakes.

Maybe it's time for me to learn something new - even if it was it your expense - sorry for that.

I will second the need to check the locating pins from time to time. On one of my front brakes the pin was almost a full turn loose. Easy enough to do whenever tires are rotated.

I was thinking it was the brakes because the one pad (inside right) was grabbing and making the whole rim hot to touch after about maybe a half hour of highway driving (I never tested this). I was thinking that the one pad would cause the tire to "turn left" slightly and cause the wear on the inside of the tire.

Of course I could be completely wrong and making a fool out of myself

Hi Dave,
That pad that has worn down more than the opther pad is proberly due to the caliper slide pin being seized on that caliper. It causes the pad to stay against the disk, instead of moving away, causing the uneven wear.
Grease the slide pins with a high temp grease, when you assemble them.

An I thought I had a monopoly (and if you turn out to be right, I might still have it all to myself).

Done and done. I've been running the new brakes for a couple weeks now. There was a bit of rust on the pins that I was able to remove. No doubt they were seizing!

Going to check the fronts tomorrow.
