Hi Alex,
Now I’m no mechanic, but you mention in your last post that you’ve driven through some flood water, the air intake is set pretty low
Its not low ,unless the air intake has been modified. In standard form, it's routed from the airbox along the top of the passenger inner wing via a flexible hose, behind the inner wing carpet. However, if you have a FRP airbox mod fitted, yes you could have sucked in water because the air intake is then set low. If that's happened the engine will need rebuilding /replacing as the pistons or rods will be damaged,
Provided you have fuel ( press the shrader tyre valve in on the lhs of the fuel rail under the plastic cap) to see if fuel under pressure comes out and put a spare spark plug on the end of a lead, the outside of the plug threads earthing on the metal rocker cover , get someone to crank over the engine and see if that plug is sparking .Then report back with your findings for further advice.
Alex I would start as previously mentioned by checking you have a spark at the plug .
The fuel pump should buzz for a couple of seconds when the ignition is on but not with the key as far as cranking the engine. If not check the reset button for the fuel pump in the passenger lhs footwell hasn't been activated.
The gearbox breather has an arrow on it , many people mistakenly fit it back the wrong way around.
Doing so will cause oil to be forced out of the gearbox . So when you get your replacement the arrow must point to the front of the car.
Check that water or oil from a leaking rocker cover gasket isn't sitting around the spark plugs, because that would also prevent it from starting.
