No, it is not recommended to drive your truck with a bad fuel pressure sensor. The fuel pressure sensor helps measure the amount of fuel in your vehicle's engine, and if it is malfunctioning or broken, it can cause serious damage to the engine. Without this vital information, the computer will not be able to adjust its air-fuel ratio properly and will likely run too lean or rich. This can make your vehicle unreliable as well as increase emissions levels which may fail an emissions test. In addition, a faulty fuel pressure sensor could also lead to poor acceleration and overall performance issues due to inadequate combustion. Therefore for safety purposes and optimal performance of the vehicle, we highly recommend getting the fuel pressure sensor replaced before driving your truck again.
