Buddy of mine truck is running wild, what i mean from wild is your typical APPS symptoms. He told me he had the code pulled.. forgets the code number.. but tells me it says Injection pump low meter. Then he tells me when he pulls out his MAP sensor the truck runs fine. IDK what to tell him. A code would be a good start. Anyone here anything like this
 
He pulls the sensor out or just unplugs it?
 
Sounds Like the board on the pump is dead.... or the MAP sensor is bad.
