These JTd,s are usually very good.
Is there any clear pipe in the fuel line to see for air?
Do you have a hand primer you can pump before trying to start?
Are you using pump diesel or any additives or bio fuel?
Other than that if no codes are showing its a trip to a diesel specialist, try connecting a little bulb to the heater plug cable and place it so you can see it to see if the plugs work when its startingmor not starting, that should point you away from that area if its working ok

Shouldn't need glow plugs at this time of year,
assuming your UK that is.........
And you don't state hot or cold starting.
So,providing it's not fuel supply,
I'd suspect the crank angle sensor,
I've had 2 in with identical symptoms,cranking fine but no firing,
And a CAS failure doesn't leave a fault code,as far as the ECU can tell the engine isn't even turning over!
Of course both of the ones I had in would not cooperate and worked fine when testing,
Even the 'scope was no use.
So working on logic I replaced the CAS on the first one,result!
never failed since.
Same thing on the second one when it came in.
So your call,
faults like your can be tough to find if they don't present when testing.
Oh and I fitted really cheap CAS's from Amazon,less than £20 if I recall.
If I had to gamble I did not want to shell out for O/E,
almost a year later and they're still running!

Could I make a request or suggestion to other members of this q+a section.

Most posters here have basic, little or no knowlege of automobile mechanics,and I'm sure will be baffled by terms we use in the garage.

Can we try and keep the answered simple in plain English??
Please don't be offended by this

I stand corrected.
But in defense I thought I had "simplified" my answer.
Guess not.
Must try harder.

Wasn't meant to take it personally. I'm sorry. I'm talking to everyone in general.


General public won't understand terms we use in the trade and abbreviated words .

Sorry! Plz understand
