Can ignition switch cause no power to fuel pump?
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
What would cause a fuel pump not to turn on?
If either due to a faulty crank sensor, or ecu, the crank sensor signal is not being read, the ignition and fuel pump systems will not power up. Also, a faulty ignition module can create the same issue. Check for signals from the crank sensor and other sensors.
What sensor controls the fuel pump?
The fuel tank pressure sensor is part of the fuel pump assembly and is mounted on top of the tank or inside the tank. It's part of the evaporative emissions system (commonly referred to as “EVAP”) and reads pressure in the fuel system to detect evaporative leaks, such as a loose or faulty gas cap.
