Noise when waiting for glow plug?
Happy Holidays All,
I have a 07 f250 6.0l King Ranch with 130,000 km/s on her.
When I turn the key and wait for the glow plugs to heat up there is a sick sounding hum. It sounds like a fuel pump to me, but it is my first diesel and thought I would ask you all if this sound is fermilier to any one. The sound is there humm is there always when I turn the key to on, but sometimes it sounds real bad.
Thank you all in advance,
Stretch8z

Normal.
Wait for it to end, and also for the heater light to go out, and then some more --- 120seconds is the glow plug cycle --- before you crank.
If it is really cold, turn off ignition after 120 seconds, and repeat cycle for 120 more seconds.

Merry Christmas and Happy New Year to you !
Welcome to FTE !
u r correct, it is a pump and although most say wait for it to finish,
unless I'm using the remote start which delays for 30 seconds (I think) ,
I'm too impatient and never wait
101K later it still starts and runs fine !

The loudest sound is usually the vacuum pump. There is no need to wait for that to go out. Second loudest is the fuel pump. I cannot hear that one from inside the cab, but my ears are not as good as they once were. No need to wait for that one to go out either. The only thing you really wait for is the glow plug indicator, and a little longer if you feel the need.

You can, but the 120second glow plug cycle heats up the combustion chambers more if you wait.
Where I am, it is cold.. I do another cycle to be sure.

the glowplug timer is up to 120 sec so 2 minuts. The light and the timer are not set to go off together. A short duration light is normal. the longer you let it heat up the happer it will be when it lights

Have you drained or changed the filters lately?
I had the same problem using B20 a couple of years ago.
The filters were overdue, the temperature dropped and the fuel became thicker.....noise that grew louder. I changed the filters and it went back to normal. I am not sure if it shortened the life of ether the pump or the injectors.
Hope this helps.

"It sounded smooth before now sounds like it has a galstone!! LOL...." isnt this the sound of the ficm doing its warming of the injectors? and the change in sound means check the voltage? <!-- / message -->

I never thought the FICM could have caused the change in sound but maybe you are right and the OP should check the voltage of their FICM
