truck wont start
 

Hey guys, my 90 cummins had a leaking injector pump, it leaked from about 4 spots. So I got one of a 93, it is turned up and 3200gov spring. I had it put on and when I started it, it white smoked like crazy, it sputtered and popped and backfired. It hazed really bad, like smells like raw fuel and burns your eyes, its blue. This morning it wouldn't start at all, I had to put on charge and go against my code and spray ether, it started pured white smoke and popped, sputtered, and backfired. When it warmed up it stopped white smoking and just hazed but still sputtered when revved up. It will start pretty good when warm too. A lot of people are saying my timing is way off. Is it easy to adjust?
