Its sounds like lightly and fastAll 4 injectors fire at the same time only on cranking.
Later, when ECU pics up position of the pistons and camshaft, injection will be done by each cylinder.
I really, really doubt that oil can make up for lost compression.
No matter how drained it is and no matter how long engine has not been started, that is no reason for no compression.
Shot in the dark.
If your camshafts are turned for 180 degrees, engine would behave like you described.
Everything is OK and in place but the spark fires at the end of exhaust stroke instead of compression stroke. Even then, some combustion should take place, even in the exhaust pipe. But that is the only thing I can think of. Also would explain lack of compression. Of course there is no compression if the valves are open.
How hard is it for starter to turn the engine? Normal load? Or is it turning the engine lightly and fast?
The Camshaft ends by the Gearbox side. the Small half circle is closer to gearbox. Down and the bigger half circle is on top. When locking camshaft. and TDC
. Is that correct ?
