Idi fueling problem

My 94 idit does this thing where it will sputter for a couple mins and smoke then it will just stop it’s completely random I put new injection lines and put a new return line kit and still no difference, could it be injectors or injection pump?

Did you try the old ATF in the fuel filter trick? That would help dislodge any crud in the injectors or IP.

Just fill the filter with ATF, start the truck and run it for about a minute. Then shut off the truck overnight and let the ATF work its magic.

You can also do this with diesel fuel additives like Diesel Kleen or Hot Shot's Secret, etc. Whenever I put on a new filter I fill it with Diesel Kleen and let things soak as long as I can.
