Hey Scotty,I have a 1999 Chevy Silverado with 189k miles on it. I have trouble starting the vehicle first thing in the morning, it cranks too long before it starts. If I turn it off and I start it the second time, it'll start right up perfectly fine, but hours later it'll still take long to start.
I replaced the fuel filter, spark plugs/wires, mass air flow sensor, fuel pressure regulator.
What else could it be?
did you measure fuel pressure before replacing all that stuff? or after?
You said it was running lean a few months ago right.
@imperator I Just Checked The Fuel Pressure...It Says It's At 40psi
Have your performed a diagnostic scan for codes and live data?

You didn't say what model or engine you have, but that sounds low.
@imperator my bad, It's The LS with the 5.3 v8
Yeah so according to specification, you want
55-62 psi
