i think the problem was with with the ignition, if you get the wrong positive the voltage droped to give the starter moter more guts,it might be doing the same to the coils too. i think he just put another relay in.
check to see weather when you crank the engine that you are getting enough power to your fuel pumps. my mate had a problem the same , power droped droped below 5V , couldent getfuel preasure
