We have a "new" (to us at least) Macgregor 26M sailboat with a Suzuki DF50 engine. When I tested it our first time (changed plugs, fuel filter, impeller) it started fine and seemed to run ok. I was hoping to run it 15 minutes (on the hose of course), warm it up, change oil....etc and have it ready for first try.
Nope. Can't keep it running now.
What I've done:
Any ideas? Do you think my idea is on the right path? Fuel starvation from a pump not working?
Someday, we'll try to sail/motor this thing, but just throwing money and frustration so far. :-(

Nope. Can't keep it running now.
What I've done:
- Swapped hoses (all new from new tanks)
- Replaced water separator
- Added a ball valve to select tanks.
- Replaced fuel filter in engine
- Replaced the female fuel connector on fuel line to engine (the male side on the engine is next when it arrives)
- Replaced and gapped plugs
- Seemed to have a clogged "pee" tube, got that cleared and water flows fine (when the thing ran).
- Prime engine until bulb is firm.
- Flip up high idle lever
- Start engine - sounds like it's trying to run, but won't.
- Sometimes runs a few seconds and dies.
- I don't see much fuel running through the filter
- When key is in 'on' I hear a very faint click in the engine.
- Very faint sound from the high pressure fuel pump
- Checked voltage at the plug - verified 12v for 3 seconds after turning key on.
- I'm thinking the high pressure pump is faulty, and only runs when motor is moved/tipped enough for some fuel to get into the line to the engine
- How loud is the pump when its running and sucking fuel before starting?
- I'm sure I have heard the whirring pump sound from our ATV, Motorcycle, Bayliner...when turning the key.
- I think it should have a noticeable sound, but not hearing it.
