Do you know that a faulty fuel pressure regulator can cause a car to stall while you were driving? However, stalling can also cause by a vapor lock. Now, how will you know if the stalling is cause by a faulty fuel pressure regulator or vapor lock? Let’s do the car problem diagnosis.

Car trouble symptoms: While you were driving your car it suddenly stalls.

Auto Specialist diagnostics: When a car stall while driving the first fault that we think of is related to a car having fuel problem. There are two possible reason that can cause the stalling problem, if the car stall when the engine is extremely hot then this means that the problem is a vapor lock, vapor lock occurs when the fuel is burned (due to abnormally hot engine) before it gets into the engine combustion chambers.

However if the car stalling occurs at any engine temperature then problem is the fuel pressure regulators. All fuel injected engines has a part called a “fuel pressure regulator”, this device is the one that maintains the fuel pressure on every fuel injectors. As usual when there is a problem on this part the engine will be starved of fuel, and if this happens the car will stall.

All about auto service advice: Bring your car to auto repair shop and ask the mechanic to check the fuel pressure regulator. If the mechanic confirms that the pressure regulator is faulty then there is no other option but to replace the parts. Your mechanic might suggest to replace other parts that are related to the problem, do not agree with the mechanic suggestion, just stick to replacing the faulty pressure regulator then observe first if the problem will get fixed, if not then that’s the time to consider your mechanic advice in replacing other parts rather than fuel pressure regulator.
