A broken fuel pump relay causes the pump to malfunction, depriving the engine of fuel. The engine may stutter, stall, or not start at all. Fortunately, you can test the fuel pump relay in a 1994 Ford Ranger without purchasing any additional special parts, relays, or tools. Almost all novice mechanics can test the fuel pump relay in a few minutes to determine if further diagnosis is necessary or if the fuel pump relay is the source of mechanical problems.
