Hi Dave, This system is in ESI, RB Key SEA 318 The fuel pump relay you speak of does indeed supply fuses 1, 3 and 40 from pin 8 F1 (10A)supplies front and rear O2 sensor heaters, F3 (10A) supplies injectors and F40 (15A) supplies fuel pump. The fuel pump relay has at least 8 pins numbered 1,2,3,4,6,7,8 and 9 as follows: Pin 1 - Pin 26 ECU (driver)(85?) Pin 2 - 30 Batt feed into relay (30?) Pin 3 - Pin 72 SRS module (??) Pin 4 - 15 Ign feed into relay from ignition switch(15 or 86?) Pin 6 - Relay earth (31?) Pin 7 - k1 50 (starter??)(50?) Pin 8 - Fuses as above (87) Pin 9 - Front interior light, to prime pump when door opened? (??) The figures and ?? in brackets are suggested alternatives to the pin numbers ESI lists for the relay. These are my interpretation so they may be wrong. Hope this helps, Mike
