CAR Won't Start

[crusacargen]

I recently did a regal to t-type conversion and now I am having problems starting my car, the engine light and coolant temp sensor lights do not work, yesterday the service engine soon light was working then right b4 I was about to put the code reader on the light does not work and the fuel pump relay stops working too. this is strange because the only reason the SES light was working was because 2 days ago my car caught a little fire in the engine bay so I hosed it down, miraculously the SES light works, the lights that my alarm usually activates does not work properly now that the SES light works. Currently my SES light does not work at all but my lights for the alarm work properly again. I really need help, anything that could lead me into any direction would be great
