the relay for the electric fuel pump on my 73 240z stays hot all the time, even when the car isn't running. what is the problem?

Do you mean 24 7 ? Has the wireing been modified or have you looked to see if the factory connections were used. I am asking this because my '73Z the pump would run anytime the key was turned and would continue to run if the head lights were on even if I turned the key to off position and the engine continued to run . My wireing has been compromised and I am in the process of replacing the whole wireing in the car. I am going to connect a pressure switch at the oil pressure sending unit and it will activate the fuel pump relay when there is 7 psi. available at the local parts store. Gary

when i turn the key on, the parking lights come on and so does the dash lights. the connections are factory. i put all my relays back in my car after floorpan restoration and now i can't figure out why the fuel pump relay is hot all the time.

The same thing with my car . Turn on the key and parking lights came on . I never solved the problem before I removed the wire loomb . You might ask escanlon , send him a PM and state the problem . He is a guru on wireing.
