I have 1985 GMC s15 pickup truck I have a fuel delivery problem has plenty of gas in the tank I just replaced the fuel pump I have taken fuel line off carb still will not pump gas out of the lines can you please help me.
The first thing I would check is the supply line to the fuel pump from the gas tank. You could have a clogged fuel pick up sock.

Pop off the distributor cap and have someone crank the engine over and see if the rotor is spining?I suspect the rotor isnt turning and something has happened with the timing chain. That would explain why the fuel pump is inop.
