Sadly have had another breakdown. After filling up with petrol I drove along accidentally with the petrol flap open cap in. Got a check engine light. Then a few misfires and eventually now no starting up. I think I may need new ignition coils. Do I just replace them all at once.
Breakdown after filling up at the pumps

Haha 100% definitely petrol
I will get the garage to get a sample of the fuel because it does seem a bit coincidental
So just a bit of an update here. Got the garage to switch out injectors and replace the alternator/belts. All went well and they got it running fine. Got a call today as they wanted to replace the oil filter saying it won't turn over. It has coolant in the back left cylinder of the engine!

Ah you have been rather unlucky, has the coolant getting into a cylinder been the cause all along? Any suggestions how it got there? I don't know these engine well enough to comment. Normally head gasket would be the first thought.
has the garage offered a hypothesis? The oil filter bit is a bit weird...sure you no want to change the oil, but not until after you have solved the coolant entering the cylinder problem....

no real explanation to be honest. At the moment I am suspicious as to whether they fitted the right oil filter.... Either way end result is the same. Cracked block meaning new engine needed

Ah jeez it gets worse. Was the oil filter changed several weeks before the problems started? Rolling right back to then....Where there any indications of any problems prior (hard starting, smoke, coolant temperature?
I'm not sure that using the wrong oil filter could result in a cracked cylinder head, bore or block. Maybe... but obviously excessive oil pressure can create all kinds of problems. Normally an engine would have pressure relief to release excessive pressure back to the sump, again I don't know these engines well enough to talk about specifics.
It's a hard case to fight, but unfortunately if the garage has incorrectly installed something, or incorrect diagnosis then they need to own it. For example the alternator and other parts fitted....if the real problem was a cracked bore, block or head. Diagnosising problems is not easy I do admit.
Back to the actual problem. I would want to see the crack, maybe see if it can be repaired. "Then of course need to figure out what caused the failure in the first place."

After speaking with the garage involved, we had a chat and could only deduce that the initial problem of an injector sticking open filled the cylinder and repeating attempts to start it cracked the bore, basically like a hydro lock scenario.
Obviously I can only go on what I have been told but it has some legs.
The bit I can't get my head round is that it ran fine after injectors were replaced. Maybe it was the heat cycle that finished the job off?

That makes sense, the oil filter bit was red herring.
Out of curiousity...the cracked bore, can that be repaired/replaced or is new engine block territory?
because it is definitely new engineThis is why your the best thank you for even speaking to them!
Driving with the fuel cap off can sometimes mess with the system, but it’s good you’re looking into it. If it’s ignition coils, it’s often best to replace them all at once, especially if they’re old. It avoids further issues down the line. Have you checked the spark plugs too?
Have they actual proof the block is cracked? It would take a lot of fuel to cause hydro lock and every crank of engine would see some fuel exited from cylinder or into sump. My Volvo has a cat that is cleaned by injecting excess diesel. Problem is that early versions could fill up sump eventually and lead to overfill but that would take a long time.
