The engine cranks not starting?

earlier it was not accelerating when pushed the gas pedal and it was parked. It had the VSA comes once start driving. While trying to clear the code manually with the pin in obd2 4 and 9, I reversed and used 5 and 16. Not sure if this has blown any fuse or relays but now the car cranks but not starting. OBD2 not powering up either. I was not able to find any fuse related to OBD2 but the cigarette lighter works, headlights work. Browsing through videos to figure out if fuel pump or PGM-FI relays are bad. Any guidance greatly appreciated.
