Default NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!

ok this is what happened number one its a 1995 dodge 2500 cummins 4x4 i had to tear my radiator and everything out to get to the timing and take all the gears out to get the back cover off because it was leaking and i did so got it fixed put the gears back on put everything back together started the truck up drove down the road turned around and started back when my truck started to sputter and sounded like it was out of fuel. and my fuel gauge doesnt work and i had forgotten that it was low when i parked it and all ik stupid as hell. but i got some diesel and dumped it in and primed it and it still wouldn start it would just blow white smoke not alot but some. i got it pulled back home and started going through all the things i do when my diesels run dry i took the fuel filter off got a new one and filled it up with diesel and cranked truck without filter on to make sure fuel pump was still bringing fuel that fair and it was i got the filter on got all air out pumped the primer and tried to start and same thing. then i unhooked a injector line and cranked and fuel come out there to i hooked it all back together and still the same thing. i was getting desperate at this time so i sprayed a lil statrer fluid into pipe running to my turbo/ intake whatever and the truck fired up but if i let the rpms drop it would die when i would push the pedal it would blow smoke and run like a great ape and start to blow flames so i immediatly stopped and re didi everything i had done with the fuel still no luck. i am clueless and need help asap plz help. could it be something with the timing? i am getting over whelmed and pissed at this

Yeah, sounds like the timing slipped to me too. You have to get that shaft VERY clean or you'll almost certainly have problems.

Timing all day! You dont have to tear everything down again just pop off the oil fil tube and #1 dv holder and with the proper tools youll be done in 45 min. Be sure to clean the heck out of that shaft, and when I timed mine I replaced the lock washer and torqued the nut to 185. It hasent slipped at all, but also be reminded that you cannot tighten it to much or you can "pull out" the pump shaft

try your fuel heater. mine would lose prime if i let it sit overnight and it turned out to be air that was getting in through the electrical plug in the fuel heater. it is an easy thing to get rid of since its a problemed part
