![]() Many engine problems like these often go unnoticed until it’s too late, sometimes leading to complete engine overhauls or total losses. One reason for an engine’s inefficiency is a partial or complete failure of the vehicle’s fuel injection system. Engine surging without the acceleration engaged.Power loss while driving up a slope or when towing.Some common symptoms of a failing fuel pump include: When the pump fails, it cannot deliver a steady flow of fuel, interrupting the engine’s mechanical function. Because of a clogged filter’s restriction, the fuel pump might need to work much harder than its design allows. This contamination could stem from the fuel source or internal corrosion inside your fuel tank.įuel pump failure frequently occurs due to a clogged fuel filter. If your filter experiences excessive clogging or needs replacing faster than usual, the root problem could be contaminated fuel. The filter’s primary role is to prevent harmful substances like sludge, metal particles and other debris from entering your engine. Owners should address even the most minor concerns right away, as some issues - like contamination in the fuel system - can lead to more significant problems later.Ĭlogged fuel filters are often one of the early indicators of diesel fuel contamination. However, your vehicle’s powertrain control module (PCM) triggers the check engine light when the system operates out of the ordinary. Some of the most common symptoms to look for include the following:īecause some vehicle owners do not notice an apparent change in performance when their check engine light triggers, they may not prioritize maintenance. These indicators often mean the diesel isn’t burning as cleanly as it should.Īnytime an engine runs differently than usual, one of the first areas you should consider is the fuel system. Some of the most common signs are a loss of acceleration, random changes in speed and excessive sputtering. ![]() Vehicle owners often notice contamination when the fuel affects performance. Symptoms of Bad or Contaminated Diesel Fuel Damage to fuel injectors, lines, pumps and solenoids could result in higher fuel consumption, power loss, hard starting, poor idling or smoke. Areas of concern include clogged fuel filters, a malfunctioning fuel pump, injector failure and more. Water, microorganisms, dirt, debris and other potentially harmful particles can contaminate your fuel and lead to severe system damage.
