can an over powerful fuel pump blow out fuel pressure sensor

Hello, no, the fuel pump will produce a fixed amount of pressure. If the line has been compromised, or the sensor -- then perhaps something could become detached. Help can be provided by a local repair facility. I would not recommend repairing this on your own, as fuel leaks are serious business and a safety hazard. Fuel pressure can be tested with a pressure gauge at the fuel rail by a professional.
