So I need some help and info on some issues on my 2011. I had my wife take it to a local quick lube for a oil change and fuel filters. The shop owner called me and said he broke a peice on one off the filter but was going to replace it but the part was gonna be here today. So he gets the part and replaces it but after it was done when he started the truck it started throwing a bunch of codes and running really rough. He called a couple mechanic shops in our area and was told that maybe the housing was cracked causing air to leak into the fuel so he replaced that and no luck he's having one of the shops owner come help him try to figure it out or just take it to his shop if he can't figure it out the codes thrown are in the pics along with one that didn't store that code is (p0884) I'm reaching out here in hope someone else has dealt with a similar problem after a filter change and could give me some insight, tips, solutions, or guidance to get this taken care of any help would be really appreciated thank you.

 

Hello,
The codes don't make sense (to me) for "fuel filter replacements"?

P1291 - Injector High Side Short To GND Or VBATT - Bank 1, and 1292 is the same except 'Bank 2'.

I would first find out exactly 1.what all they broke, then 2. all the parts they replaced, along with 3. where they obtained those parts. These trucks only like genuine Motorcraft, especially so when it comes to fuel filters, caps, pumps, etc. If they got them aftermarket from local parts store, you may end up chasing your tail.

You want to be careful at this point running the truck to much without it getting proper, non-aeriated fuel, since lack of lubrication (diesel fuel) could damage the Hight Pressure Fuel Pump (CP4).

Since you have the 2011 model, like my truck, it has the primary pump on the driver's side frame which Ford calls the DFCM -- the diesel fuel conditioning module >>> filter which includes water separation and WIF sensor/primary low pressure fuel pump.... if you want more info on that, let me know.

I'm wondering if the broke the injector return line fitting, which is a "Tee" fitting in the OUT hose connector, which is made off of plastic. That's a common fail point... got this pic from here.



When I searched "6.7 Powerstroke P1292.." this came up "6.7 Powerstroke P1291 P1292 which yielded this link.... which had this link in a post. Another link... scroll down to bottom also, more links with these codes...

The earlier trucks like yours have separate fuel sensors in the factory steel line that feeds the CP4 high pressure pump... here's a pic of the filter bucket which holds the secondary filter, the fuel feed (from DFCM) line connector (IN), the fuel (OUT) with the injector return fitting (Tee) and the separate fuel pressure sensor and the fuel temperature sensor, to give you a better idea of what is going on...



Those codes are weird and are injector related like Scott said... you need to find out exactly what was broke and they need to make this right, because it sounds like the truck was running fine prior to this...
