Thanks Guys! You were both right; spark. Now running. Very pleased 😃. I pulled the plugs, they were wet with fuel & soot gunge even after several days of not attempting a start. (Plugs not in fantastic condition to be honest, turns out they were original BMW plugs with 120k km on them). Brushed them up, dried them off & pumped a shot of engine oil into each cylinder via a plastic tube as @Spinner99 suggested and boom! Engine started (& yes, loads of smoke produced which was impressive). Engine light & a "misfire" code from one of the cylinders for a a few mins while warming up, then a good drive and now all seems well. Will purchase a new set of plugs next week, will see if I can find a more cost effective way than the $300 for a set from Repco. Thanks again guys, awesome. Good advice, really appreciated!!👍.
