Hi.
Sadly I have the same problem with my 1997 non vvc 1.8 MGF.
Mine did not break down, it just decided to never start again after changing the iffy ignition switch (lights would flicker touching the key and would fail to start or stop after a second, cycling the immobilizer would get it to work sometimes).
So also have spark, fuel pump primes and feeds under cranking, plugs dry= no fuel injection.
This system has a live feed to the injectors and 2 wires return to the ECU (middle row top and next one down), when the ECU earths these the injectors fire. Used a probe to do so, they clicked and car would attempt to start. Triggering the injectors in test mode via the ODB port also did this.
So the injectors work and the car will run when they do so, but the ECU will not tell them to fire.
Lucas 5AS can shut off these so thought this was at fault sent it to ( https://www.technozen-electronics.co.uk/mg-rover-5as-alarm-ecu-services/ ) and he reports it tests ok, so sent him the ECU in case it had lost pairing and that has also tested ok with no faults or lost communication reported.
Have changed engine relay, fuel relay, coil, leads, cap (had some corrosion), rotor arm, fuel filter also tested fuel cut off and removed and cleaned crank sensor (though will be no spark if this fails-have spark). Disconnected fuel line attached a rubber hose into a 2l bottle, on prime it filled the hose, with a 2 second rank had 1 1/4" of fuel in the bottle and good solid flow.
Onlt things I have now not done are a new wiring loom, new fuel pump or an exorcism.
What the hell is going on?
Can anyone help?
