Need help 6.4L SuperDuty

[hetner1102]

I have a 2008 SuperDuty with the 6.4L Diesel. About 5 months ago I added a H & S mini maxi tuner, DPF delete, four inch, with five inch magna flow from there back. Last week I added a Air Dog FP100 lift pump. I have driven approx 500 miles so far, and last night the trucks engine light came on. I waited till I was home to pull codes and glad I did, now truck won't start. I am getting the following codes, P2563- turbo boost control sensor circuit, P1635 GM- Volt ref circuit, P0232- Fuel pump secondary high. This is my only means of transportation, any help would be appreciated.
I did contact H&S, they did some checks with me such as setting programmer to ICD Display and fuel rail showed zero while jumping brown wire to battery with key in run position. By turning the key the truck does nothing, unless jumping that brown wire by the washer fluid. I also called AirDog, they stated not to connect power wire to fuse box, connect it to yellow wire where OEM Liftpump was. I did that also, I am stuck, what to do next, truck won't start. I received great feedback from all involved, but know everyone is like me, we all need help. Please help me. Thank You in advance.

Have you put the truck back to stock and tried to start it? My truck shut down the other day and the Exh. sensor was bad. Would not let the truck start at all. Had to have it towed to the dealer.

Exhaust sensor

Do you know where that exhaust sensor is located? Is it in the turbo down pipe, or up bythe turbos. I have had the DPF delete on for a while, at least 5K in mileage, my DPF/cat delete has no bunts in it so I just tucked them up under the frame, covered them with plastic and electrical tape incase I ever needed them again. Please let me know, thankw

Those are the two you would need to look at. Check them and make shore something did not happen to them. The only other thing would be the Air Dog FP100 lift pump has made a problem. What I could not tell you. Unhook the batts. for five min. and clear all the codes. This will reset the computers then see if it starts up.

Thank You, at this point I am willing to try anything. I appreciate your help. I'm kinda glad it happened now, we pull a 40 FT fifth wheel, don't need these issues going to Ocean City, or Florida next year. Do you know if this is a common occurrence, will it be something that needs cleaned yearly etc....... Because of the DPF/CAT DELETE?

Same happened with me, Exh sensor goes bad and it shuts the truck down for safety, and will not restart, pretty unfortunate.

And dangerous too. I loss power steering, brakes. If I had a trailer that was loaded this could have been really bad thing. This should not happen this way. Truck should have gone to a limp mode and killed the fuel petal.
Just my .02

A great big Thank You

Dog man, just wanted to thank you for all your ideas and knowledge. Believe it or not after 3 days lying on my back, changing everything back to stock, including my DPF AND CAT, and backed my tuner to stock, completely unplugged still nothing. At this point I was going to loose my mind, so I decided to step back, have a beer, and said WTF, the only thing not changed is my air dog. I put my stock pump in, disconnected my air dog and wha-lah, truck ran. Redisconnectd my CAT, DPF, and put my tuner back in and all is well. I am sending my air dog back.
Just so u know,he customer service at air dog is a frickin joke. The head honcho there for tech took 3 days to call me back, then had no idea. I have been dealing with WCPDIESEL, JJ there, very friendly, customer oriented, and more knowledge than the idiots at air dog. I would not recommend that pump to anyone. Again, thanks for all the advice.

Thanks to you too.

My problem was with the air dog, for some reason it either quit working, flow to slow, etc....... Put stock frame tail pump back in and what do ya know, fired up right away, all I had to do was purge air from the lines. Thanks again for your help and ideas.

Glad you were able to get it going again. It's a good habit to get into, is to start at the last thing you installed and work backward. Most of the time it's less work...lol
