The tell tale sign of a vehicle that is running too rich is that it’ll have black exhaust smoke. Black Exhaust Smoke – One of the most common symptoms of a vehicle that has a bad fuel pressure regulator is that it’ll run rich.Most of the time, when there is a fuel leak, it’ll be accompanied by the sharp smell of gasoline. Beside the loss of power and fuel economy that this can cause, it’s a big safety hazard. Leaking Fuel– If any of the seals in the fuel pressure regulator fail, or if the diaphragm fails, raw fuel will begin to leak.Without a proper air/fuel mixture, the engine may run rough, misfire, hesitate, or fail to start at all. Either way, this wreaks havoc on the air fuel mixture. Misfire– When the fuel pressure regulator fails, it can allow too much or too little fuel into the engine.Here are a few of the most common symptoms of a bad fuel pressure regulator: A Typical Fuel Pressure Regulator Bad Fuel Pressure Regulator Symptoms: Ford TaurusĪ bad fuel pressure regulator can put your Ford Taurus out of commission. Too much fuel pressure can ruin injectors. It also saves wear and tear on the injectors themselves. Think of it like a damn with a river of fuel behind it.
