Finally got one pump, easy to fit, a bit of simple work, but works a treat, looking for a second one now, only really cheap (at high price) Chinese ones around, genuine are $800 here, good after market are $300, but I could only get one, so far.

Sounds like the engines are getting cold start fuel with closed throttles and no bypass air. You can smell fuel when cranking so start there.

Seems like when I turn the key to on, there is a very short dzz, but no real pump running sound (whirring) and at key back off, the same dzz seems a bit hard to believe both pumps are bad at the same time?

Yep, going to do that later today when my “helper” comes home. It seems strange I can smell fuel when trying to start, but then, who knows? Do you think they would at least kick for a second even if the HP pump (on both motors) were dead?

Take the cowls off and wait there to listen to what happens when someone else turns the keys to the on position.

Pair of 90As won’t start
Got a bit of a tricky one, I have a pair of 90As that have been not started for about a year (various personal reasons) fresh fuel, turn over fine, but, both will not start, the only thing in common is the single safety cutout, I have disconnected that, just the same. The motors are behind a transom “wall” so I am unsure if the HP pump turns on, but, I can smell fuel when trying to start it, any simple clues before I start pulling things to bits? The motors do not even “kick” just turn over via the starter.
edit……..no codes shown, motors go through standard start procedure.Tags: None
