Does the starter crank the engine over? Did you use a scanner to place the injector codes in ECM? Do you have security light on dash?

Customer: replied 1 year ago.
the truck cranks over fine, i have no dtc's, yes i have a security light, everything in the cab works as it would any other time
Expert:  Tool Hut replied 1 year ago.

Does security light go out after a few seconds or does it stay on? If it stays on try a VTD learn. Document attached

Customer: replied 1 year ago.
it goes out after a few seconds

Did you use a scanner to place the injector codes in ECM?

Customer: replied 1 year ago.
i was not aware that needed to be done. the injectors i replaced the old ones with had the same numbers, also after i got the new ones installed and primed the fuel system the truck fired up, i let it run for approximately 30 mins, let it sit for an hour, it started right back up, then i went to take it for a test drive and on acceleration it started blowing white smoke and died on me, havent been able to get it started since, i noticed my supply and return lines in the engine bay had been kinked, i bypassed that part of the fuel system by running new lines straight into a can of diesel and still nothing
Expert:  Tool Hut replied 1 year ago.

Ok. I apologize I thought it said 05. The 02 does not have a glow plug module so you don't do a calibration. The white smoke indicates it is lean. Do you have a scanner that you can monitor FRP?

Customer: replied 1 year ago.
i do not have a scanner to see what the frp is, i have been trying to find one i can borrow as i cant afford to take it to a dealership to have it hooked up. i assumed that the kinked lines might have been the problem that is why i did the fuel can and separate lines but couldnt get anywhere with that either.
Expert:  Tool Hut replied 1 year ago.

did you bleed it after the fuel can?

Expert:  Tool Hut replied 1 year ago.

I am going to opt out as I cannot dedicate the time you will need to diagnose this properly

Hello and welcome to JustAnswer!

You have a bad injector. The white smoke you saw was from fuel leaving the engine unburned. The reason the engine cranks but doesn't start is one or more injectors are either returning excessive fuel or fuel is leaking into combustion chambers while cranking. If the system isn't sealed then it will prevent fuel rail pressure from climbing high enough while cranking for the injectors to be turned on.
