Oldsmobile Alero engine won't keep running despite new fuel filter, wires, air filter, and plugs on Oldsmobile Alero

Some Oldsmobile Alero owners report experiencing engine stalling issues even after replacing the fuel filter, wires, air filter, and plugs. These problems may stem from a loss of fuel pressure to the injectors, potentially caused by intermittent fuel pump power. Additionally, some owners have encountered issues with the Mass Air Flow (MAF) sensor, which can send erroneous signals to the engine's computer, triggering the check engine light and contributing to stalling. Faulty spark plugs or wires in the ignition system may also play a role in this issue. To effectively diagnose the problem, owners are advised to check for spark at the plugs during cranking, test fuel pressure to ensure adequate delivery, and monitor fuel pressure behavior for signs of fuel system malfunctions. By following these steps, owners can identify the root cause of the stalling and take appropriate action to resolve it.
