So does it start again ok after you let it cut out or only if playing with the coil or metering unit? If not and it runs fine otherwise I.E you can drive it ok but it just won't idle by itself I should think you have an idle issue. IIRC I am sure RST'S don't have ISCV remember they are MFI not EFI! If it's revving ok I should think the fuel pumps fine, usually with the relay problem it won't start at all due to the faulty relay and hence no fuel pump! Again the green wire breaking usually results in a no spark situation as well!

Certainly do not bridge the relay as a solution, it's wired through a relay for multiple reasons, the main reason is due to the amount of power the pump pulls, if you use sub standard wire to bridge the two this will melt! Another reason is the pump will only run when the engine runs and so if you were to have an accident the pump will not switch off when the engine stops like the standard setup would!
