Hello, first I want to thanks everybody who regularly share amazing info here. The info I found here helped me a lot in the last few years. Today I am a lost. I got an 11 350 coming in for reduced power about 2 weeks ago. Went on the road and the truck ran good until going up hill at full power then it died and would never restart. No rail pressure. Got it towed back and found injector#5 mechanically stuck open. I replaced inj, #5 witch was cover with carbon from top to bottom and got truck started but ran on 4. Got code for contribution #6. found injector short to itself. replaced injector #6 and got truck started running on 8. drove outside and went to take off but truck died. Restarted on 4. Had code for contribution #3. I could never prove the injector or the harness wrong but everytime I would disconnect it, I would get back on 7. Hotline recommended to replace it anyway and also recommended a fuel system as we have pink fuel. ( farm fuel in northern Canada) I replaced #3 injector and truck started on 8. Went on the road and truck would drive perfect on 8 with good power on moderate throttle. As soon as I would floor it, I would loose a bank and get code for contribution#2. The truck would not restart. At this point I had a mechanical fuel gauge and could verify my low pressure was checking good as well as rail pressure. I went and disconnected #2 and truck re-started on 7. Reconnected #2 and it came back at 8. I took a sample of fuel on the driver's end of the fuel rail and apart from being pink, the was no special smell to the fuel, neither then metal nor rust on the control valve. I decided to drop the tank and flush the system. Having a bigger sample now it appears the it smell like varsol (confirmed by everybody who looked at it.) I put fresh fuel in and flushed the system through the lift pump return line but truck is still acting up dropping bank. I left it idle and lost the other bank (not the one from injector#2. but no codes for this one. As running on 4, if I floor it, it stall and I get a code for injector #2 short to high side and cam position sensor. The gasket tab on the egr cooler is already folded. I think the injectors may just have been damaged from the bad fuel and fail one after another but as my service writer gets chewed by the truck's owner, I though I would take a chance to quiz you guys. Any help would be appreciated event if it it just to say that bad fuel destroy stuff and that I will need a fuel system regardless. Thanks for reading my novel!
