Would an old fuel filter cause your car to stall out then start but die again when you put on the gas?

A clogged or dirty fuel filter can restrict the flow of fuel to the engine, causing the engine to stall or hesitate when you press on the gas pedal. This is because the fuel filter is responsible for removing impurities and contaminants from the fuel, and when it becomes clogged, it can no longer do its job effectively. This can lead to the engine receiving a insufficient amount of fuel, which can cause it to stall or run rough.

To determine if a clogged fuel filter is the cause of your car's stalling, you can try replacing the fuel filter and seeing if that resolves the issue. If the car starts and runs smoothly after replacing the fuel filter, then it is likely that the old fuel filter was the cause of the problem.

It is important to note that a clogged fuel filter is not the only possible cause of your car's stalling issue. There could be other underlying issues, such as a faulty fuel pump, a bad fuel pressure regulator, or a problem with the fuel injectors. If replacing the fuel filter does not resolve the issue, it is recommended that you have the car diagnosed by a qualified mechanic to identify and fix the root cause of the problem.
