Second thought, if the car has not been running for a while, all the hydraulic valve lifters could have bled down... so multiple fail to start paths in operation at once. Valves not opening. Fuel not primed to injectors. Missing run components: Suck: Collapsed lifters so not enough air to compress Squeeze: No air to compress [and make heat] plus, no fuel to ignite [injectors dry and bled down] Bang: No bang happens because of the lack of the first two. Blow: I note quite a lot of blowby when you take off the oil fill cap.. if the exhaust valves are staying closed, the spinning cylinders would pump whatever air is in the cylinders past the rings and pressurize the crankcase.. since the valves are not opening to exhaust, which I suspect is what may be happening..
