Well over the past couple days my truck had began to act up while driving it....It started out just running extremly rough of a cold mornin....even after letting idle in the driveway for 15-20 mins it would pop and crack while going down the highway.....This seemed to get worse eveyday....I changed the fuel filter and made sure the lift pump was properly workin... I drained the tank thinkin i had some bad fuel..., refilled it and added some fuel conditoner, i unhooked all the boxes thinkin that they might be have went bad.....I have about 22 psi fuel pressure at idle as well.... The day i done all this it was about 50 degrees and the truck ran a little better but not quite like it should....Later on that night when it was about 30 the truck got to where it wouldnt even run at all.....Now when i start it, it idles tons of black smoke and has a very weird idle....Could this possibly be a bad injector, CP3 pump or just a sensor......thanks alot.

 

Your not running bio are you?

 

Any codes? Turn the key from off to on ( not cranking) 3 times , ending in the on position. Codes will read out in the odometer screen.
