We have a 2014 Ram 3500. We are hot shot drivers and use our truck to pull a 40 foot trailer. Today we had a load for 6000 pounds and was going 60 miles an hour out of nowhere we lost power and now the truck won’t accelerate more than 30 miles an hour. If we’re going up the hill it goes less...

I have 250,000 miles on the original injectors in my 06 Cummings turbo, and had heavy black smoke coming from the exhaust, and was told it could have been a bad injector, ended up replacing all six injectors and fuel tubes. But now I cannot get the truck to start whatsoever. Any suggestions?
