might be just the leads worth a try.... just pull the leads up a little so your making the spark bigger just rest the leads on top of the plugs

is their petrol coming out of all the injectors as these can sometimes stick ,especially if lying up

get a set of testers and make sure the injectors are firing might be a dogey wiring loom,if your getting spark and the plugs are dry and the other injectors are firing i would say its your loom or worse case maybe the ecu playing up,

what ecu are you running and is it tested

Check all four injectors have power with ignition switched on, if good try moving a known good working plug in the affected cylinder(s), remember just because a plug sparks outside does not deem it a good plug, under far more stress with compression etc inside the engine...

As the plugs are not wet, remove the fuel rail leaving the injectors plumbed in/wired up and see if all 4 inject, as said if having been laid up a while they can get sticky, get someone to spin over whilst you tap them with a spanner, this will restart most stuck ones, or just get them checked/ultrasonically cleaned, this would be a good idea anyway.
Next if all 4 working check spark side of things.
