2005 chevrolet silverado 2500hd gasoling engine 4wd, how do l change the oil pump?

It will be a diesel oil only, with a viscosity rating of 15w-30 or 20w-50 depending on the ambient temperature of your area. The brand is immaterial but it has to be diesel oil to have the ingredients needed to run a turbo. Oil used in a petrol engine will not be suitable for this application.

Check the fuel pressure from the fuel pump.

If the engine is not making any kind of engine knocking ( rod bearing ), then you be alright with just the oil pump and oil pick-up screen, hope this was very helpful.

on the back of the engine close to the firewall by the glow plug controller is a high pressure oil switch. if this switch goes out diesel fuel will not reach the injector pump.try pulling the molex and jumping it out with a wire. if it starts. replace the switch. it takes an extra deep socket designed for that switch that can be purchased at any auto supply. good luck!

Depending on how technical you want to get try e-bay or a local book store. They would have a good choice and alot of different types you can purchase.
