Hey guys, 2000 yukon xl 6.0L 4x4 I have a problem here. Trying to start the truck, cranks but doesn't fire. Checked the relay, its connecting. opened the gas cap, still nothing. Hooked up scanner, no codes. Probably fuel pump. Heres the question. Whats the special tools required to do the pump and does anyone have a breakdown? I usually take the total labor time for a trades person and double it... any suggestions before I start dismantleing... thanks for the advice in advance.
