In fact .... come to think of it ... isn't an electric fuel pump supposed
to be powered through an oil pressure switch or something?

Correct. The only time the fuel pump is supposed to operate is when there is
oil pressure, or the engine is cranking. It's pretty simple to figure out
why. That is unlike an automobile fuel pump that starts to do it's thing
when the key is simply switched on.

Good idea. However, wouldn't an improperly seated or disengaged safety
lanyard clip result in no power to the engine, including to the starter?
ILUVMYBOAT stated that the starter engages and tries to turn over the
engine. Am I correct on this?


I don't know on I/O's. I know that on the outboards I've had, the engine
turns over, but because there is no ignition power, it won't start.

It's been a while since I had an I/O.

Boat electric pumps also work for a short time when the ignition is turned
on. Just like a car.

Maybe some do, or maybe things have changed, but I remember the one I had
only ran once oil pressure built up and a oil pressure switch made ....
which it would just by cranking a few times.

Otherwise, if there is a fuel leak, and the pump runs, trying to build
pressure, the gas gets pumped into the bilge.

Not a good thing.

Electronic fuel injection pumps usually run for a couple seconds when the
ignition is first turned on to build up pressure. At least they do on cars,
I'm assuming they do the same on boats.

Not supposed to by Federal regulation.

They should be wired such that they run *only* when the starter is engaged
or a oil pressure switch is satisfied.
They should *not* run .... even for a short period of time .... with the
ignition "on" but the engine not running.

I wonder if that includes outboards?

I will have to recheck mine next time I use it. But I think the fact you
turn on the ignition is part of the starting procedure. The run time is
very short, short time delay relay I think.

Is your boat engine fuel injected? Maybe the "rules" are different for FI
versus carbureted engines.
