I recently had the stern drive on my boat serviced. The engine is a 2000
Volvo 4.3 Gi/SX. I only had the stern drive serviced.

The week prior to taking it to the dealer, I changed all my filters
including the fuel filter, changed the engine oil, and changed out my sea
water impeller. I ran the engine repeatedly both before and after my work
and it was as smooth as could be. The fuel tank was full and I stabilized
the new tank of fuel prior to putting it to bed for our brief winter. I live
in Northern Calif so it was only put away from 1 Dec to early March.

After returning from the dealer I tried to take the boat out for a brief
run--no start and not a hint of sound coming from the fuel pumps. There
should be a 2 second priming period prior to turning over the engine.
Nothing, Dead. Not a hint.

I'm in the process of troubleshooting. I can't find any disconnected wires
or connectors. The battery is good and fully charged. The engine turns over
just fine. I reset the 50 amp circuit breaker (it didn't appear to be
tripped). My wiring diagram shows 4 other circuit breakers but I don't see
them on the engine itself. I'm on the way to work to pick up a digital
mulit-meter to check for power at the fuel pump electrical connections but I
thought I'd ask this group if there was something obvious that I might be
missing.

Taking the boat back to the Volvo service center is a 3 hour round trip so
if I can get this on my own, I'd like to do so.

Thanks,

P

May sound silly, but it happens more often than people admit:

Is your boat equipped with a safety lanyard?

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.

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

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

All it takes is a kid flipping the switch. Don't ask!

My I/O would turn over but not start.

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.

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.
