*Update* . . . so my brother had his truck taken to a "different mechanic" than the one he originally talked with . . . lo and behold - replaced the lift pump, and all is fine !! . . . Shocking to think there are mechanics out there robbing people the way the original one was going to do ! . . . Good to have the FSM and then understand how things are supposed to work, so you can diagnose ! . . .

Cheers,
