Electrical problem for the fuel no power
A lot of newer vehicles have a fuel pump cutout switch on the engine. If the engine shuts down for any abnormal reason, it loses oil pressure and one of the things that happens is the fuel pump is cutoff. This is a safety item in case of an accident which shuts off the engine. Check for the oil pressure cutout switch on the engine, which is usually different from the oil pressure gauge or light switch. Can't say exactly where it is, sometimes on the upper rear part of the engine behind intake manifold or on lower side of engine right into the block. The fuel pump run circuit is different from the fuel gauge circuit although they usually run in the same wiring harness if the fuel pump is in the tank. If the pump is not in the tank then the fuel level sender in the tank is probably defective and should be replaced.
