Idle "Squeeking" sound on V6 TRD sp

When my engine is warm, at Idle, I hear a squeeking sound, kind of like a strap sound that goes away as soon as I step on the throttle. Anyone else? Will definitly go to the dealer about this.

 

HPFP. Most truck either do or will have this problem. (V6)

 

So is this normal? Or something I will have to get fixed What is causing this?

 

It's normal. It shouldn't be, but most people have or will have this issue. It is the fuel pump under the hood specifically for the high pressure direct injectors. If you switch to an ethanol free fuel, it will stop. I can't get ethanol free here in the DFW metroplex, so I just have to deal with it. Sometimes it's worse than other, and sometimes I don't hear it at all. I'm going to run she'll fuel for a few tank, then try chevron. I know QT is bad already.

 

It's normal using fuel with ethanol. Use E0 and the noise goes away.

 

Winner winner chicken dinner

 

Interesting... I don't have that sound and I use 87 cheepo Sunoco ethanol gas all the time.

 

After the dealer changes out pumps on some guys trucks the problem goes away.

 

Turd gen problems

 

I thought it was mice re-arranging seating positions for ride.

 

It actually sounds like baby birds in their nest waiting for their mothers to feed them!!!

 

I went to the dealer, they replaced my fuel pump and also another pump responsible for another "Noise" They said there was a TSB for those 2 items. Just the fuel pump itself goes for $1500 retail....And I think that they replaced it with the same exact part number (not an improved one). I do not think I will buy this truck after my lease ends....
