It is important to check everything else before you do a costly and perhaps unnecessary fuel pump replacement. Look for electrical problems, bad wiring, a short, split hoses, a vacuum leak or a clogged fuel filter.

As winter approaches, it’s good to note that one of the leading causes of fuel pump failure is running on a low fuel tank, especially in cold weather. Frequent driving with a low fuel level can starve the pump for lubrication and cooling by plugging up the strainer with contaminants inside the tank, which can lead to accelerated wear or even pump damage.

Today’s automotive technician is a well-trained individual with a vast array of technical skills that are similar to those of a structural or electrical engineer due to the ever-changing technical aspects of the automobile.

The functions of today’s fuel injected engines rely completely on a powertrain control module (PCM) and its associated sensors, of which there are many. Fuel has the ability to adapt to altitude, temperature, humidity, and load while maintaining a constant fuel ratio of 14.7:1.

In order for the PCM to prepare fuel flow strategies, it uses sensors to determine the demand on the engine and its operating environment.

The throttle position sensor (TPS) is a potentiometer located on the throttle body and attached to the throttle plate opposite the throttle linkage. It has three wires: battery voltage, 5-volt reference, and a signal wire. Its purpose is to signal to the powertrain control module (PCM) the amount and speed of the throttle opening. This is an indication as to the demand placed on the engine at any given time.
