Hello, a couple of days ago, I have accidently cut a wire of my oxygen sensor on my catalysor, that had provoced a big spark and the car had stop. Now, I know that:

-the fuel pump doesn't work because I have disconnected the gaz hose when I crank the engine and nothing happen

-the fuel pump fuse have power

-fuel pump have power (checking with multimeter

Than, it is my fuel pump the problem, and why it stop working with a spark from oxygen sensor

Thanks for your help !!!
