Check the fuel pump relay.

I reseet the relay inside of trunk and fuel cut off button it worked for a little bit then went back to running even when engine is off. How do I reset the brain on this car

The relay might be faulty, did you test it? Try replacing. TO clear the memory , disconnect the negative battery cable for 20mins and reconnect.

Not sure how to test it. I'm ready for a stick of dynomite and a match...lol

I'd just replace the relay, about $15.
