Yes
Replace the priming pump in the fuel tank (submergable)
Costs about £120 & is not the same as the petrol type I think you'll find
There are a couple of earlier threads if you search for them

Worked for mine so I guess we need TB's undoubted wisdom on the issue

All 3 TD's I have had did this. Less than 20-25 litres and a pig to start, over that and no problem.

Its most annoying and such a common fault yet there seems no official line on a resolution!

Er, just a thought. Have you spoken to Vauxhall to see what they have to say about it? I know it's probably a stupid idea but sometimes.........

Never had this problem, and sometimes let it get down to the low fuel warning light coming on before refueling.

Neither have I since changing the tank pump. Sometimes it just runs on the smell!

My 97 did this - I replaced the injector leak-off pipes because they were rotten & the problem improved (didn't disappear totally). My 2000 hasn't done it yet - and I have run it down to almost empty on a coupleof occasions.

I have exactly the same problem.
Changed leak off pipes even put a none return valve
in the main feed to the filter so as to keep a head of diesel
but has made no difference to the poor starting below 20 litres.

Mtek - check Fuse 18.  And relay that controls fuel pump.

Also, bleed the fuel filter, in case of air lock.
