I have a 99 K1500 w/ a 5.3L. What is the operating fuel pressure supposed to be? I was told be someone that is should be around 60-65 PSI and mine has tested at around 50. The reason I started looking into was that my truck doesn't always start right up, sometimes I have to pump the gas peddle to get it going. I have been thinking that it is either the pump or a regulator. If anyone has ideas please let me know.
Thanks.
Steve
