Ineed some advice. Correct me if I am wrong but when I turn my ignition to the on position I can hear the fuel pump on but it never shuts off. Is it supposed to do that or is something wrong. Please help. 1984 300zx non-turbo 5-speed.

i think it should shut off after 30 seconds... there's a thing on it in the online manual...
