Weekend Mechanic host Bruce Bonebrake examines the fuel system of a Ranger pick-up truck that won't start. The project includes doing a fuel pressure test and checking the fuel pump relay to locate the problem to the fuel pump. After removing the truck bed to expose the fuel tank, Bruce removes the pump and replaces it with a new electric sending unit/fuel pump assembly. Then he retests the system, looks for fuel leaks and reinstalls the truck bed. A test drive confirms the successful repair.
