Re: No power to fuel pump on 2006 crownline 305 (?) mercruiser
Thank you for replying, I'm in northern ky.
Before anything was done the fuel pump was not getting power. Turned key on, no power to fuel pump, pulled fuel line and no fuel was pumping. So that's when took small pc of wire and ran from battery to fuel pump and it started working. So my problem is not getting power to fuel pump.
Assuming this is a carbed engine and not MPI, the fuel pump isn't supposed to run when you turn the key is on. It's a safety feature required by CG regulations.
The fuel pump should come on when you crank the engine over with the starter, and once the engine starts the oil pressure builds up and an oil pressure switch closes and allows power the pump. There is no pressure switch in the fuel pump however, it should keep running as long as there is power to it.
Here is a wiring diagram that shows the wiring for the electric fuel pump.
I have moved this to the Mercruiser forum
