Will crank but doesn't stay running?

If your engine cranks but doesn't stay running, it could be due to several issues such as a faulty fuel pump, a clogged fuel filter, or a problem with the ignition system. Additionally, issues with the air intake or sensors, like the mass airflow sensor, may also cause the engine to stall. Inspecting these components can help identify the root cause. If you're unsure, it may be best to consult a mechanic for a thorough diagnosis.
