Have you checked the leak off pipe at the back of the diesel pump and the blanking cap on number 6 injector..Also how long do the glow plugs get power before the power goes off ....

I think he said 12 seconds

The length of time the glow plugs are on for depends on the temp as read by ECU temp sensor. Twelve seconds is a bloody long time if it's not well below freezing.

I re read... its 10 secs, he in Brighton... its always hot there... almost tropical

I usually get 5 seconds no matter what the outside temp is - I have replaced the temp sensor twice with new - just to double check - made no difference. Pulled glows 1& 2 so far today - both light up.

Well you did put 10... 5 is normal

Checked glow plugs direct off the battery - they were new 6 months ago and a good make - yet 4 out of 6 not working!!

Possibly the Delphi's made in the factory across the road from the factory somewhere in China that Delphi have their genuine ones made.

The thing about brand named goods it they are always the first to get copied and faked

Couple of members have had problems with them recently. One of mine had snapped in half inside. Bought mine from Island a few years back.

New plugs, starter motor and battery - now starts on first turn! Combustion gas still escaping round the injectors - know this as oil seeping from oil cap has pooled around injector base and you can see it bubbling. Doesn't seem to effect running of engine so I'm going to leave alone for now. Thanks to all for helpful advice.

Cant you anneal the injectors so they sit better?

As Dopey says you can take out the injectors remove the copper washers heat up to cherry red and let cool and refit, what you don't want is a build up of carbon going passed the seals making future removal a pig.

I usually drop the washers in water to cool. Dont forget to Copperslip the threads and torque to 65 Nm (48 lb ft)
