  1. In this video we show the step by step process for changing the high pressure fuel pump on Cliff's 2014 Silverado with the 5.3L EcoTec V8. This issue is related to fault codes Powertrain P0172 and Powertrain P0175. The exact issue is fuel being blown past the HP fuel pumps seals and into the crank case which contaminates the motor oil. If left uncorrected, this can damage internal components as the oil will break down due to the fuel and lose its lubricating ability. ?? LINKS TO PURCHASE TOOLS & PARTS FEATURED BELOW?? A quick indicator that the fuel pump is likely at fault is a smell of fuel when removing the oil dipstick. The high pressure fuel pump failure was verified by a local dealer by monitoring the fuel trim levels. I was very surprised to find out this the high pressure fuel pump is not covered by the factory power train warranty. Especially since it is literally driven by the camshaft, directly affects the health of the motor, and the codes literally read "POWERTRAIN". GM really should get their act together since this appears to be such a common problem. Note that the fault code did clear itself after a few starts of the truck. Fortunately, this is a pretty straight forward job that only requires basic tools. The process showed in this video should be identical on 2014 through 2018 Silverados and Sierras with the 5.3L EcoTec V8 These steps should also be very similar to other GM models with the 5.3L, 6.0L, and 6.2L such as the Tahoe, Suburban, and Escalade.

I have listed it here because GM includes it in the recommend parts for this job.
