Took truck to dealer for long crank problems... They updated to the newest flash and when they went to refire it stumbled on the 3rd crank when it is supposed to start and fired on the next three... The tech diagnosed the problem as a bad transfer pump in the fuel tank.... Truck has had this issue for 1.5 yrs and I finally had enough so I took it in...

So who thinks the pump is the culprit.. I am seriously doubting it... But hoping it is..

 

Well I got the truck back today and they said without a doubt they are sure that the pump in the tank was bad and they also replaced a little Return Control valve on the injection pump... They said that was part of issue why it would lope out real bad when on high idle... We'll see tomorrow morning when I fire it up if they did a good job... They even washed the truck for me too!!

 

Sounds good! hope it works out for you!

 

Let us know the outcome. Haven't heard of too many in tank pumps failing.

 

Well, mine did!
