As far as I can remember there is a green/yellow wire that feeds both the injectors and coils.This wire is fed from a relay under steering coloumn. Check that this relay is getting a ign feed. If not, feed it from the ign switch through a fuse. I have had this many times when I worked with a Diahatsu dealer. Also as mentioned, give a good check at battery live fuse links.

Hope this helps.
