yeah i just put a new fuel pump in the front tank. it has been bad for a while and i have been running on the rear tank. when wife ran out of gas these symptoms started. i figured she burned up the rear tank since it seems to not get fuel. I replaced the front tank pump since i needed to anyways. Now it runs the same on either pump. Checked fuel pressure and it seems ok. Truck ran fine until she ran out of gas. i have checked all lines and cannot find any trash. any suggestions?
