Fuel pump running after shutting off truck

[rbyeatts]

I have a 2003 F-250 and recently took it in for the recall on Control Module Recalibration. The truck runs fine but when I turn the truck off the fuel pump purges for 30 seconds. Is this normal?

I just got the same upgrade and was told thats a new fix to help keep the injectors clean...

I've been lurking on this forum for a while so I figured I'd chime in on this one.

My 05 F250 recently had the 05E16 recal done and the pump runs a good 20 seconds after shut done as well. I'm going to call my dealership to comfirm a post I read while searching that stated it's to clean the injectors. It sure seems like an excessive amount of time.

the fuel pump is not runing ,the new module calibation that just came out cycles the injectors for thirty seconds to clean all oil ot of injectors to try and help wit hcold start concerns and try and eliminate premature injector failure,wether this is a fix i dont know ,bu it does seem t help with cold start rough running complaints

[kid2texas]

i thought it was the injectors and not the fuel pump, it just seems 20 seconds is a long time but if it helps the injectors then its a good thing.

I noticed mine is doing it as well. Don't know why either.

yep from all ive heard the newest reflash cycles the injectors after shutdown

I had my 05 in the dealer 2 months ago for some ruff starts. They replaced 2 injectors and upgraded the injector program. That fuel pump noise is the injector program draining the oil off them. On a different note I told the dealer I had a weird whine like an old powerglide tranny. Sure enough it was the turbo. Thank god for the psd 100k warr. as I dont have the extended.

i think i might need that reflash, i have an 2006 f-250, it runs rough when cold and hard on start up, i have made a post in motor problems could soemone help me, how do i know if mine fits into the recall for the computer recal?

i dont think it is a recall that mail was sent out to bring ur truck in-im pretty sure u goto the dealership and tell them u have a cold start problem and ask about the updated flash to make sure they do it.id say that will take care of it
