  1. Have f-450 2007 ambulance.When off idle ,power balance shows

    1,3,5,7 cyls wack.Ran the bubble test as seen in the article section ,but saw no bubbles.Customer states that when it warms up,problem disappears.Passes koeo and koer test and buzz test.fuel presure good under load.Performed ficm update,believe it or not this had never been done,Truck seems to run better when cold but not solved.This leads me to believe I have some bad injectors.REmember something about fuel rail dampener sticking,broke causing issues on one bank.What do you guys think?

  2. Things have been bizare here lately.I had an f-250 that had an intermittent no start.customer had towed in twice.no codes and

    starts every time.Hot,cold or driven everyway I can,cannot recreate concern.Made recordings,tested ect......Finally installed vdr.Next day comes back.Look at recording and see low

    icp.What the f--k?Fix was dummy plug,but customer never wanted to leave truck.Why never any icp code/s?Hotline say's"I don't know."Anyway,now have 05 excursion that I replaced ficm for low

    voltage codes 611 and all cylinders with low injectors.This fixed that problem and I returned truck to customer.This was on the 22nd of Dec.Now truck back with no start.Say's was never fixed the first time.Mind you this truck bought used and out of warranty!Going through the same sinario again.I do not like for things to beat me and will work till the death.What would you guys do in these situations?At the end of my rope!

  3. I have one that is intermittently a no start when cold.Once had a p2614 of 2617.Can't remember.Cleared those codes a while back.I know the tsb concerning loose mini fuses can cause a no start.This morning would not start.It finally started,but ran poorly and smoked for a few minutes.The temp was right at freezing.Got into shop and runs good.Checked mini fuse and found number 18 mini fuse a little loose,but wiggling had no effect.The warmer the truck gets the tighter the fuse seems.This is an 05 f-250 with 98k miles.It also looks there has been dirt on top of all relays and fuses in box.My question is has anyone seen this on a very cold morning,or does this sound fimilar.

  4. Hi Bruce,

    Did verify the map,baro and ebp all close.Removed the ebp and tube,but no blockage.Fuel pressure is at 45 at wot.fuel quality is good.Oil looks good and is full.Made some recordings and sent them to hotline.The weirdest looking thing is the egr looks wack proportional to ebp.icp looks steady.Inspected that connector also.Customer did state no problems before turbo failure.Other dealer stated shaft and impeller,turbo vanes destroyed.Did not find anything in downpipe.Thanks for the input.
