So I fixed my spark plug fouling issue by installing new valve seals. Plugs are dry!! But now the truck started something new. It only starts on second try. First try it starts then looses idle and dies if I don’t give it gas. Then today I was parked nose up and it would start even on the second try. I drift back level and it finally started. I tested the fuel pressure at the rail and it was 30 psi with key on not running. Turned the key again and pressure went to 40. Turned key off and it maintained pressure. Does this sound like my pump is going bad or something else? Truck runs great otherwise. Well….except for the passenger side valave cover gasket that started leaking too. Oil all down the right side under carriage. Always something with these trucks! Thanks.
