GM GMC 2500 pickup: My shop put in 5 diesel fuel pump ejection

Customer Question

My shop put in 5 diesel fuel pump ejection pumps in a year in my 1994 GMC 6.5 torbo. He claimed he went from fuel tank to cylinders found no other problems. Once the fuel get to diesel fuel does not come out as needed. Truck has no pickup and stalls. Is it maybe wiring harnesses or computer ?

I assume that the injection pumps he is getting are coming with a new PMD. Do you know whether they are or not?
