Suzuki Grand Vitara turning over but not starting, runs briefly before cutting off after fuel pump and spark plug replacement on Suzuki Grand Vitara

Some Suzuki Grand Vitara owners report experiencing issues where the vehicle turns over but fails to start, or runs briefly before cutting off, even after replacing the fuel pump and spark plugs. These problems may stem from the new fuel pump not functioning correctly or from fuel delivery issues, such as a clogged fuel filter, which can hinder engine performance. Additionally, some owners find that the spark plugs, despite being replaced, may not be the correct type or properly gapped, leading to further starting difficulties. Electrical system problems, including a faulty Engine Control Module (ECM) or malfunctioning crank sensor, can also prevent the engine from starting or cause it to stall shortly after running. It is recommended for owners to verify recent replacements and seek assistance from a qualified mechanic if issues persist.
