Doblo 1300 multijet 2008 starting problem

[Stovesweep]

Hello everyone, thanks for letting me join, I have what seems to be a not uncommon problem with starting my van. I've had ot 10 years and it's been a reliable workhorse up until now. I have now a very annoying intermittent starting problem sometimes it cranks, sometimes it don't. Sometimes it cranks but won't start sometimes it cranks but does start totally unreliable.
So far these items have been replaced
Battery
Starter motor
Ignition switchwith new chipped key
Transponder ring
Any help would be really appreciated I am getting suicidal

May be totally unrelated , but I had a 2014 Vauxhall Combo 1.3MJ (Doblo) that would stop at a junction when you dipped the clutch and die out and wouldn't restart until you locked and unlocked it again. It had Stop/Start , but that has never worked before or after the fix.
In the end I traced it to the clutch pedal position switch, the tag had broken off that follows the pedal action.
Easy enough to fit if you get your head up under the dash with a flat screwdriver, they are a bit flimsy so be careful.
I did a diagnostic and it showed up on that.
You could try the lock and unlock bit to see if similar issue.
