Hey guys after 9 years of the truck sitting, I got the injection pump rebuilt and no more air getting into the fuel system! The truck is drivable and starts right up.
The issue I'm having now is low power, I changed the oil/filter and air filter, that helped a good amount but the truck still struggles to get to and maintain 100km/h, it will lose speed going up any incline as well.
Should I look at blocking the EGR? Any other things I can try?
