93 dodge cummins no key or dash power and smokes really bad plz help
 

I have a 93 dodge d350 cummins it lost power to the key and the dash but the door ajar beeper works and lights as well and the 4 ways the neutral safety is bypassed good and its a manuel so you do it under the dash and the fuses,ignition,wires, look good and are all hooked up but the truck was being rolled over then the key lost power i know these trucks real good but idk this problem or another it has.

Bad throttle hesitation and smokes an backfires out the exhaust
 

The truck has a good idle but it is a constant blue haze and it leaves a black spot on the ground where it axle dumps its fuel related and it burns your eyes its got good fuel lines, injectors, timing, fuel filter, and a new reman injection pump. The pump that was on it was good but you cant replace backside of ksb solenoid seal toward the block without pulling it and even with that pump not being messed with. It did the exact same thing hesitation,exc. The fuel tanks clean and a electric fuel pump did nothing different the timing cover was off and all the gears aligned and the new pump key did not fall out or anything. But we took it to a shop and they figured still timing idk how it would be but they said you could get more rev before popping when they advanced timing to the head then thats when the ignition and dash lost power so now im stumped.
