Corsa VXR crank but no start (fuel issue?)

[Lewisjsm]

Hello, long shot but someone may have an idea.  2009 Corsa VXRacing Z16 LER cars been off road for a year.  Engine ******, replaced with a second hand engine along with lots of new parts and started first time.  
Put about 50ish miles on it without issue.  Parked up and left for a week or two.  

Started to move across driveway  but was spluttering and cutting out a few times then died and now doesn’t start.  Will wind over all day long but not even a cough.  

Tried starting it on brake cleaner and started straight away telling me it’s definitely a fuel issue and not spark.  Checked fuel lines for leaks and whether fuel was coming out which it was but only when cranking.  Replaced sender unit and fuel pressure regulator and hasn’t made any difference.

Any ideas much appreciated

First thought would be crankshaft or camshaft position sensors - even stretched chain/belt which can lead to sensors being out of sync.
However as the engine fires when sprayed with brake cleaner then I would look for any fault codes, engine compression, even oil quality can affect starting (washed down with fuel, etc which lowers compression)

Battery voltage, earth points (leads and connections) in fact there are so many other factors that could affect the engine not running.
Start with the basics and go back over your work as it may be something simple that has been overlooked.
