Will a mass air flow sensor prevent a car from starting?

Dirty sensors will impact whether your vehicle starts. An example of this is the Mass Air Flow sensor or MAF. The job for this sensor is to let the computer know how much air is in the engine. If it sends a signal that the pressure is low, the computer may prevent the engine from starting.

What happens if you unplug the MAF sensor?
