Last night on my way home my truck lost power gradually and barely made it home, this morning I start it up and bluish smoke is coming out the tail pipe with a low and rough idle, went to drive it to my shop for repair and trucks power could not move truck more than 10mph with foot to the floor, engine will not max out RPMs at all with foot to the floor and in neutral, I get rough sluggish response. Now truck will not start, anyone have this same problem before?

 

That is the symptoms of a plugged fuel filter. That would be the first thing I would check.

 

Found out it is the injection pump went bad, if anyone knows of a 7.3L idi turbo motor with a good injection pump on it I need one bad, I cannot locate one that isn't special ordered and they want $350 for. Thanks if anyone wants to buy a nice truck for $5,000 with a $350 fix let me know
