Truck ran fine before i rebuilt it

Answer
i would have to take a look at this one several things come to mind

timed wrong-busted regualator check pressure to find out-wired wrong-sticking injectors-shorted injector wire to ground causing injector/s to stay open (have seen this several times-engine coolant temp sensor unplugged or shorted-good luck.
