Hi spong
the device on the side of the pump is a type of waxstat. when engine is cold and ignition off it should pull the lever over to its stop which turns the camring inside the ve pump to give cold idle advance. When ignition is on there should be battery voltage to the connector on back which warms up the waxstat and allows lever to move to normal running position. if pulling lever over cures cold running issue try adjusting the cable to pull lever over when engine off and cold then power up the stat to check it fully returns. Does the truck still pull as well as it did b4?
