Make sure your fuel pressure is correct.
This happened recently on my truck. I installed a new Bosch pump when the original pump failed. The truck then ran extremely rich at all times. I checked fuel pressure and found 85psi when it should have been 35-39 psi. The fuel pressure regulator was bad (it wasn't bypassing the excess fuel back to the tank)and after changing it out all is back to normal.
