What farts?

[Agnem]

OK, strange post title, but it is the best thing I can think of to describe it. When I turn the key on, and wait for the glow plug light to go out, I hear what to me sounds like some kind of fart, a few seconds into the cycle, like a valve releasing vacuum or something. What the heck is that?

I'll bet you that's your glow plug relay on the way out.... Any hard starts lately?

It's the air being pushed out of the foam in that leather seat ....

Fuel pressure regulator on the drivers side /top of the fuel filter housing (under that fancy plastic Powerstroke engine decorative cover that I don't have). When you turn the key on the electric fuel pump starts building pressure and when it hits about 50 PSI the regulator on the return line opens......sometimes making a "farting" noise.

Could be that too, forgot it was electric on these, it's on the passenger front fender well. Also could be the ABS module in front of and below the drivers side battery.

Out of curiosity I just checked my truck and all 3 areas make a little farting noise when the key is turned on waiting for the glow plugs with the ABS being the loudest........Guess I need to quit feeding her burritos

i figured it was the vac pump mine does the same thing. though i never wait for my GPs this time of year.

Glow plugs??? heat index of 105??? i don't think so!!!

Barking spiders.

Mine does that to but sounds to be on the drivers side or dead ahead. Rule out GP relay. Mines new & it still does it.

oh yeah. They run them for smoke control

Ah. Electric vacuum pump. Didn't notice that yet. Guess that is needed for the HVAC. That and the ABS sound like likely candidates. I didn't think there was anything wrong with it, just wanted to know what it is, so when it stops making that noise.... I'll know where to look.
