Can a MAF sensor cause a no start?
Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can’t adjust these symptoms on the fly can cause the engine to not start. An example of this is the Mass Air Flow sensor or MAF.
Why do I need to troubleshoot my MAF sensor?
You can hardly diagnose a MAF sensor on symptoms alone. Other faulty components, like the fuel pump, fuel pressure regulator, and vacuum system, can create similar symptoms. That’s why you need to troubleshoot the MAF sensor (and related circuits as needed) before replacing components. 2. How the MAF Works

Do you need to replace fuel filter when replacing fuel pump?
The fuel level sensor is a separate component attached to the fuel pump. This part does not always come with the fuel pump and sometimes is not interchangeable with aftermarket fuel pumps. Chevrolets have a common issue with fuel filters getting clogged. You always want to replace the fuel filter when replacing the fuel pump.
