I've owned my boat, powered by the little Vetus m2.04, for 4 years. I've always started the engine on about 1/4 throttle. It's always started straight away, no problems. Today it coughed and spluttered for a couple of seconds then died. Tried again, same thing happened. More throttle, same thing happened. Full throttle, it threw out a fair bit of black smoke for a few seconds, then ran as normal. I switched off and left it for an hour, the same things happened again.
Fuel filter changed 50 hours ago. I undid the bleed bolt on top of the fuel filter assembly, fuel flowed as it should.
Any ideas what's going on?

It could well be a duff heater plug.
Remove the feed and busbar between the two plugs, get a multimeter and set it to ohms. Measure resistance between the positive terminal (the one the nut goes on) and the body, you should have around 0.5 - 0.9 ish ohms.
Be careful removing the old ones if you need to replace them, plenty of love juice - plusgas, GT-85, WD-40 what have you and a gentle loosen tighten sort of effort, slowly slowly catchy monkey and all that.
Removing snapped heater plugs can be a ballache of the highest order

Black smoke= blocked air filter, faulty injector or faulty injector pump in order of cuntiness.

Meanwhile a squirt of Sniff might help. (Easystart ether spray).

Better bet with poor starting diesels is a blow lamp up the intake manifold, a CI engine ignites the fuel by high compression pressure and in the case of an indirect injection engine with the aid of a bit of heat. Much kinder on an engine to put some hot down its throat than blast it with some ether. |

Removing snapped heater plugs can be a ballache of the highest order Thanks for that. I've just had a look, forgive me for being a numpty, but I assume the heater plugs are the 2 things that look like mini spark plugs, with a single wire feed to one, then thick folded wire (busbar?) to the other one? So, it's disconnect the power supply and folded wire then measure the resistance between the positive terminal of each heater plug and the body of each heater plug, is that right? |

Shouldn't need to use glow plugs to start a diesel engine at this time of year, even my ancient BMC gets a few months respite from them in the Summer. |

Yes, that's the ticket. They need measuring individually hence the need to disconnect them Ignore stabby, test your plugs and go from there, they are by far the easiest and cheapest thing to sort first. |

Ignore gazza, the air filter is by far the easiest and cheapest thing to sort first. |

Ignore gazza, the air filter is by far the easiest and cheapest thing to sort first. It may well not have one..... The chances of a bird or mouse taking up residence in the filter if it does have one is vanishingly small. Ricco says this has developed recently. Odds on its not the air filter (if fitted) I've replaced absolutely filthy filters on engines that started absolutely perfectly. Go and have a yorkie and lob your Haynes manual on the fire 👍 |

My engine doesn't have an air filter. It just has a metal intake, bit like a funnel. If I can't start it then (Vetus dealer 5 miles from here) do I just need to blast a load of heat into the filterless intake? Do I need to go easy on this, or just blast away with the blowtorch?

My personal recommendation is that if his boat is fitted with an air filter then the very first step should be to temporarily remove the filter element and see if the engine starting improves. |
