Bogging down, backfiring and white smoke

Bogging down, backfiring and white smoke
My first time on here and need some help. I have an 03 3500 with 5.9L 6 speed manual transmission. Recently my truck started to bogg down in 4th and 5th gear at around 2100 RPM. I changed my fuel filter hoping that was the problem but it did not resolve the issue. Next had my batteries tested and they were both bad. Replaced them both in hopes that was the issue causing the fuel system to not run at full pressure. Did not fix the issue though.. my friend who is a mechanic came out and hooked up his computer. No trouble codes and all injectors are working properly. He seems to think the timing in the injection pump is off and therefore going out. He is coming back out with his gauges to check pressure in injection pump and lift pump. Truck is getting worse and now I notice a lot of white smoke coming from exhaust when it starts to sputter. It also will backfire with some nice flames. Anybody here encounter these issues or have any help? Thank you in advance

It's my pot and I'll stir it if I want to. If you're not careful, I'll stir your's as well!
As Pat said.
How does your mechanic know that the injectors are working properly? What tests did he do to come to that conclusion?
Did you check for oil in the rad water?
Are you sure that there is no gasoline in the diesel?
Maybe time for a compression check?
Is the air filter clean?
When you eventually discover the real cause of the problem, please do not forget to post back so that we can all learn something.

Cool, at least he is acquainted with the common rail.
I am moving this to the 3rd gen section to get better coverage, this is an emergency, I'm broke down in BFE area and not everyone looks here.
Keep asking the questions and these guys will be able to help.

thank you. I appreciate all the help I can get. I also use my truck to haul cars and when I'm loaded or going up hills the truck is affected more. Thanks everyone

Overfueling? Check your oil level and give it a good sniff. A stuck injector will allow the fuel to wash down the cylinder walls, flow past the rings, into the oil. It would appear as your engine 'making' oil.
I'd also recommend you not drive while 'loaded'.

Checked what pressure? Pressure from the lift pump and that's why you installed the FASS fuel system? If so, you should should check your rail pressure to see if your CP3 is putting out what it should.
