Too Afraid to Ask

Fuel pressure is how much force the fuel has in the lines that send it to the engine. If this pressure isn't right, the engine might not start or run well.

Technical Definition

Fuel pressure refers to the pressure of the fuel in the fuel rail, which is essential for the engine to start and run properly. If the fuel pressure is too low or too high, it can cause starting issues or poor engine performance.
