Topic: fuel pump on all the time issue

[jjccp]

My car is a 1977 280 SE. Right now the fuel pump runs all the time with the ignition switched on and engine not running.

I thought that in the past the pump would turn on at first and then off after a bit. Maybe when the pressure built up?

Can someone tell me the right set-up and what needs to be repaired?

Thanks in advance,

Jim

This is a safety issue, so if you have a car crash and the ignition stays on then the pump will continue pouring gas somewhere, which otherwise would stop if the engine stalls.

Probably your fuel pump relay is broken or it does not exist and has been jumped by a wire. (As is the case with my SL and it never bothers me)
