I replaced the cps on this truck 2 months ago. Like I said before, I had a under valve cover harness that had come loose. After repairing the harness plug the truck runs much better, yet is still has a miss and is a little down on power and the ses light is only on when the engine is running. I am pushing the boss hard to buy a NGS scanner so I can quit wasting time on this thing. In the mean time I am trying to find out what the resistance is supposed to be on the injector harness and what pins to check against each other or against ground so I can figure out which side is the culprit. My guess is that I have a bad connection on one of the injector wires or in one of the plugs. I was hoping someone could help point me in the right direction so I dont have to rip this thing all the way down again. As you can imagine it is difficult to diagnose anything on the powerstroke with out the proper diagnostic equipment. Thank you for the input.
