I have a 2012 honda civic si. Got into the car turned key it started then died now the lights are flashing like crazy after trying to start the car.Head lights tail lights and dash lights. The car will start but then die. Will not stay running longer then 30 secs. I have changed the fuel pump, fuel filter, new fuse boxes under the hood (which had all the wires new on it) and the one in the car, and new battery. I am getting gas to the engine and only to the injectors when key is 1st turned. Its just giving enough gas to start the car but not keep it running. Also I checked fuses found that the horn fuse was blown I replaced it and now it wont stop blowing. Any ideals on whats going on????
