Ive been looking into changing my st170 from running carbs to standard injection in my mk2 fiesta, i have the inlet manifold and injectors that i got with the engine but the st loom seems to have alot of things to stop it from working, like the key and barrel & fuel pump.

Is it possible to get round everything to make it work? Like use the st key and barrel in my fiesta. Will the fuel pump work if i wire the loom it to my external pump?

Wht other problems will i come across?

Cheers!
