Hey Scotty! Love your videos and enjoy learning ways to maintain my vehicles! I have a 2013 Silverado with the 5.3 V8 and was wanting know what type of fuel pressure I should be getting at the rail. When I test, I get 60 psi with the key turned on, but not started. After I start the engine, my pressure drops to 44. Both readings are stable. Is this acceptable, or is my fuel pump getting weak? Thank you for your help.

you need to look at your fuel trim data
is my fuel pump getting weak?
I don't think so. Do you have any performance issues?
