Odyssey Posted April 13, 2021 Share Posted April 13, 2021 (edited) So my starboard engine fired up and ran today for all of 5 mins..... then wouldn’t restart. It cranks, nearly runs but cuts out.... I’ve checked fuel seems fine, there are volts, fuel pump is whirring... it’s a full EFI engine, got a mechanic booked in for Thursday to run a diagnostic check... Ideas please 🙂 Edited April 13, 2021 by Odyssey Quote Link to comment Share on other sites More sharing options...
JonC Posted April 13, 2021 Share Posted April 13, 2021 When you say fuel seems fine, how did you check it? I guess it’s been in there a few months now? Is this your first run out since the service? Quote Link to comment Share on other sites More sharing options...
Andy135 Posted April 13, 2021 Share Posted April 13, 2021 Fuel leak somewhere? Or coil packs? Quote Link to comment Share on other sites More sharing options...
Odyssey Posted April 13, 2021 Author Share Posted April 13, 2021 Same fuel in both tanks, it’s run already no issues, I’ve checked the water separator and no water. Im wondering coil pack, injectors or sensors Quote Link to comment Share on other sites More sharing options...
suzook12 Posted April 13, 2021 Share Posted April 13, 2021 Could be something relatively simple like crank/cam position sensor Quote Link to comment Share on other sites More sharing options...

Injector and coil pack more likely to go under load. Sensor just needs to be out of range and ECU says “computer says no” and sits there looking grumpy 🤣 Diagnostics will hopefully sort it out!

Gordmac Posted April 14, 2021 Share Posted April 14, 2021 I don't think it would fire at all with a faulty crank sensor, not sure about cam sensor, if it has one. Presumably those engines sense being cold and overfuel on start? I wonder if it thinks it is warm? Quote Link to comment Share on other sites More sharing options...
Odyssey Posted April 14, 2021 Author Share Posted April 14, 2021 True.... coujd be MAF, fuel flow, injectors, CDI, coils, phase of moon... Hopefully diagnostics will show sensor else its get mechanic to look at spark plugs and work back from there... Quote Link to comment Share on other sites More sharing options...

Some of the guys from CBYC have taken their boats down to Milford so I’m seeing pics of blue sea and fish on WhatsApp. I’ve got 300kg of mackerel being delivered next week so need boat up and running soon to get me out there to use all this bait 🤣 jonnyswamp, suzook12 and Geoff 3 Quote Link to comment Share on other sites More sharing options...

Ideas please 🙂 Sounds like a fuel issue, probably high pressure pump or pump filter ......... certainly something that is common to all cylinders. Could even be simple like a split hose, or sucking extra air ............. A diagnostics check will soon sort it out, or put you on the right path to the fault.

There is a fuel flow sensor harness whiz head removed to get to the fly wheel to get to the tensioner to get to the timing belt. It’s a daft place (I saw the pictures) and as the mechanic had thought he’d done it up tight but hadn’t when doing timing belt. So engine thought it had no fuel when it did.... Anyway good to go...

Odyssey Posted April 16, 2021 Author Share Posted April 16, 2021 FOC which is good. Also the honesty was nice, could of easily ripped me off and said needed a new fuel flow sensor as that’s what the diagnostics said.... He did say he hates timing belts on those engines and connecting it up in December with cold hands is always a bad idea 🤣 GPSguru and Geoff 2 Quote Link to comment Share on other sites More sharing options...
