Severe Engine problems!!

Turbo and dpf wont prevent it firing.
Unlikely to be 4 bad injectors.
Before wasting time and money put a scope on the injector wiring to see if the ecu is trying to fire them. Read live value for rail pressure while cranking. Check lift pump is delivering fuel. Get a comprssion test. Check the basics. Are you getting live values?

if you can suggest anything else or any advice would be most appreciated.
Fixing this will need somebody capable of diagnosing the problems, and then fixing them. From your post I don't get the impression that will be you. I suggest that you trying to come up with an 'action plan' to fix it is worse than useless unless you plan to fix it yourself. I have never met any competent mechanic who appreciated being told what to do by somebody who has no clue.It's conceivable that the car is beyond economic repair.
Even if it's economic to repair it, you have to judge whether the price justifies the cost of fixing it. The fact it was sold as a non runner suggests the original owner decided it was better to sell it, and they presumably understood the problem better than you do.
My advice is that unless you have the skills and resources to fix the car yourself, you should try to sell it in the same condition you bought it, for a similar price. Non runners like this are really best left to people able to asses the problem and fix it themselves. Even if you manage to fix it, it's likely you'll end up spending more than you saved, if you're paying professional rates.

An EGR valve might inhibit starting though? Mine did on an old Focus diesel. Surely you can’t do that much damage to any modern car in just 19,000 miles. Perhaps an mis-fuel but it should be easy enough to check the tank. Unlikely to be 4 bad injectors.

Doubt egr would prevent it firing, if the ngine has been sitting its clean air in there so ir would still fireEdited by Simon_GH on Friday 29th March 20:25
In this case it doesnt matter because the car is imaginary, its high gas pressure in someones brain cavity thats the problem.
Exhaust valve stuck? Turbo stuck?
Does it crank properly, does it want to start?
Check inlet, fuel pressure, compression, turbo and exhaust valves.
Start one end and follow through, in a methodical way.
If it cranks check turbo and valves then injectors. That’s what I would do. Could be ecu as well

They will stop them starting, but yes if the dpf is blocked disconnect it and try, it will be loud but will run.In this case it doesnt matter because the car is imaginary, its high gas pressure in someones brain cavity thats the problem.
