If your loosing spark and fuel you either got tdc lead issue, aei unit fail (very rare) of the relay issue weather that will be bad relay or wiring.
Check the power plug going to the aei unit too
Regarding which wires to bridge out on the aei unit relay (its sat next to it) i think it was the middle one and outer one which points upwards in relation to the relay (some pins face sideways). Trouble is most of them are yellow!
Its the main 12v feed and the one going to the aei unit to want to loop together just to make sure
