I have a 2009 Silverado 1500 5.3. Been looking everywhere and cant find solid information on what fuel pressure should be. I have 62 psi KOEO and 46 psi idling. Having a start then almost dying condition on first start of the day.

46 is too low.

I have a 2004 S-10 blazer with 4.3 and a 2007 Silverado with the 5.3. Both have 55 psi. I hade to replace the 4.3 pump last year, and the new pump has 55 psi also. Hope this helps.
