What problems can a bad fuel pressure sensor cause?

The fuel pressure sensor is one of these sensors, and if it fails then it can significantly decrease your car’s ability to supply its engine with the right amount of fuel. This can lead to symptoms like weak acceleration, difficulty starting the car, stalling, and poor fuel economy.

How do I check my fuel pressure without a gauge?
