Is your car a daily driver Or has it been standing for a while?
Personally if this was me I would check that I was getting a spark first at both of the cylinders that are affected.
If no spark then you would have to suspect that you may have a dizzy cap issue as I would doubt that two spark plugs and leads would fail together unless you are getting arcing between the two leads that are maybe a bit past there best.
I doubt it would be the rotor arm as I would think that you would have a no start problem but don't rule it out and ckeck its condition.
If you are getting a spark at the plugs, are they wet with fuel
If they are then it may point to the injectors being stuck or the ECU not sending a signal to these two injectors, if you don't have the nessecary test bulb ( Noid light) Then a test bulb will suffice, unplug each affected injector one at a time and connect your test bulb and check to see it the bulb lights up on cranking, if it does then you are getting a signal, if not then you need to suspect either the wiring or ECU.
If your getting a signal to the injectors, good
then with the engine running and being carefull you can check with a long screwdriver to your ear and the other end directly at the end of the injector where it enters the inlet manifold to check if it's firing. You should detect a distinctive clicking, if not then it may be stuck, a gentle tap with a small hammer will free it up.
If this all proves ok, then do a compression test.
Either way, please let us know how you get on
