Stalling – A vehicle with a dirty or blocked fuel filter is one of the main reasons in what causes an engine to stall while driving. A blocked fuel filter prevents fuel from traveling through the fuel lines to the engine, starving your engine of fuel. If your engine is not getting fuel, it simply will not run.

What happens if you don’t change your fuel filter?

Unless totally blocked, rarely will a bad fuel filter keep your engine from starting. On a vehicle where a fuel filter has never been changed, the dirty filter can cause erratic fuel flow, resulting in longer than usual cranking before the engine starts. Check your owner’s manual on filter replacement intervals.
