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!
Ask her to smell the smoke--sweet for coolant; diesel = obvious. coolant would be EGR cooler--diesel an injector. backfire= not good period. How many miles on the truck.
My truck backfired when it was first new and the service manager told me diesels don't back fire, and the next thing I knew they removed the pre injection and there went the fuel milage.
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.

Pulled codes. P2290Injector control pressure to low
P0238 turbo/supercharger boost sensor a circuit high
P0304 Cyl #4 misfire detected
P0478 exhaust pressure control valve high input.
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?????
