backfires
2007 F-350 6.0L, Wife phoned and said that the truck backfired a couple of times and there was black smoke from exhaust. When she stopped at idle there is now alot of white smoke but coolant level looks fine. She has about 200 km's to go before she is home pulling a 20 foot horse trailer with 1 horse. any ideas!

I think that the injectors stuck open. She went through about 75 l's of fuel in about 125 km's. Now the engine won't turn over. almost like it is ceased. Don't know if it could be the HPOP.

Sounds like it might be hydro locked from an injector dumping way too much fuel. I wouldn't try starting it again, because if it is hydrolocked that might cause some serious damage.. IMO it's time to put it on a flatbed and get it to where it's going to be repaired.

Yes, I agree. I just got to the truck and hooked the trailer to my other truck so the wife can go home. Just waiting for a tow home.

injectors are not to bad to get out and do
I just figured it was an 07 still under warreny
does number4 cylinder inject even buzz at all when you do a buzz test
dont try and start it may hydrolock

now I look at a 6.4 and it scares me love that 6.0

Check your oil level to see if it's really high. You could have had an injector seal fail and be getting exhaust into the fuel rail OR fuel into the oil pan.
The codes are kind of puzzling also. They indicate a MAP sensor and exhaust pressure sensor problem or VGT problem. P2290 is related to high pressure oil but you could have plenty of HPO and still get a P2290. Possibly an electrical problem for ALL these codes?????

Did she hit a gas station just before this happened, maybe filled up with gasoline instead of diesel?
