In need of some help

Hi I'm having trouble with my toy, setting codes po171,174 lean on both banks. I changed map sensor , I changed fuel pump with urd's upgrade kit and checked for vacuum leaks. I drive about 10 miles and codes set. I've been. Trying to get diagrams on truck and anything that would help. The dealer wants an arm and a leg to bring it in and I'm tapped from
