At the fuel rail with key on and engine running: 44.5 psi. I recall these were always lower than other 5.3 models, which were around 55. If you suspect a fuel pressure problem causing an issue, look at the MAF as well.

Ok so not to make a long story but something to check. I was getting miss fire codes and replaced every sensor and full tune up and it ended up being 1 bad catalytic converter! Fruckn pissed me off. Cranks sensors you name it were changed lol anyways, pull the 02 sensors closest yo motor and if it runs better you know you have a bad cat or both
