most likely LOW injection pressure...caused by a faulty fuel pressure regulator~....or it's vacuum source~

Here's what it looks like~

NOT the fuel pump pictured there but the small cylinder with a vacuum hose goin' to it...check to see if this vacuum hose is cracked and replace with silicone lines~

sorry for the zebra-stripey image...click on it and the zebra goes away~

have never heard of reduced fuel pressure do to a faulty fuel pump...that's a new one for me...they always Quit...Kaput>>>NADA mas~ and need to be replaced...Ain't nothin' special about it...none of it...don't let them charge you but an hour or so~....please~

faulty fuel pressure regulators will NOT issue a OBD-II code, perhaps the effects of reduced pressure makes it say "wait a minute" there ain't enough pressure here...have no idea what these genius researchers and product developers are trying to outsmart us...always~

The CEL could have come on because of an enriched condition messing up the 02, or Maf sensor (if equipped)~ get the trouble codes read by an autoparts store and bring them back and tell us, or get yer own~

the FPR has a spring, an entrance connection, a diaphragm connected to a plunger...when vacuum is applied allows MORE gasoline to circulate through the fuel rail~ https://www.youtube.com/watch?v=S5Jrwa64LDU ....sorry about the advertising~


...man that guy was a Canuck~ Don't know if the F250 also places this delicate assembly in a compromising location...but is interesting nonetheless~

you know....there are some SERVICE bulletins on your vehicle:____http://www.automd.com/recall-tsb/search? question=2006+Ford+F-250+Super+Duty
