It had to happen..after years of trouble-free service, its gone wrong! It goes through the start process, loads of smoke, then cuts out when it normally goes into turbo mode. After trying a few times on several occasions, there was then no smoke even! Checked the glow plug and it had burnt out. Changed it and we're smoking again.

New batteries, so I doubt its a voltage thing. I know there's fuel because of the smoke. Also can see the fuel moving along the line by the odd bubble here and there (which ther's always been). Maybe its the atomiser clogged up and the fuel isn't spraying very well. Does anydody know how to take it out to clean it? Failing thathit must be electrical. Anybody know what to check first?

Thanks for (relevant) suggestions, or even the irrelevant ones if they're funny.

Just spent five hours today trying to get a D3L to run ,it would go through the start up with lots of smoke, but just would not hit the high output before more smoke and closedown.

feed up because on checking fuel pump it seemed to work, anyway last resort borrowed one from a boat next door, who was in the process of installing a D2 and would you give credit, it started up, a bit Smokey at first but in no time was running at high out put and clear from smoke.

Spent most of my working life on engines, I would not have believed it, seeing the old pump and the dev being pumped to the heater very misleading !!

There is a small gauze screen under the glowplug.Despite what Kreuger tells you, it is possible to get it out and clean it. There is also a small filter in the fuel pump.

Borrow a tester if you can and this will pinpoint the problem. It shows a number and the web will list faults against these numbers. Sorry I dont know the website
 
Hi there
Your heater is not as easy as the later ones to service on a DIY basis; however it is still a practice proposition if you have a bit of mechanical aptitude and the workshop manual.

A word of caution there is a very real chance that if the heater has not been apart recently you will find one or all of the 6 mm screws holding the combustion chamber and fan assy seized; if they are they can be a real pain to remove.

I think you are pretty much on the money with your diagnosis, after a number of seasons use the atomiser and combustion chamber are likely to have a build up of carbon. There are a couple of things you may want to check before going further.

Inspect all the connections on the supply cables to the heater, as the heater pulls a considerable current while starting.

Check the fuel filter in the fuel pump; unscrew the aluminium hex sided end from the fuel pump, the filter sits in the body of the pump.

If those are ok then it could be that the flame detector on the heater body has failed and the heater is shutting down just as combustion is established, more likely though is it just needs a service.
