Turbo 2000 fuel pump not priming...Help Please
As per title the fuel pump on my MY00 is not priming. Taken the pump out and thats working,Fuel pump relay is clicking (also swopped it with the blower fan relay) Im thinking something to do with the sigma alarm. I do remember having a problem with this years ago but rang subaru today and all parts are obsolete..Any advice would be greatly appreciated...cheers

If the relay is switching then I'd assume the sigma must be supplying current to the relay. When my immobiliser cuts in I hear a relay click and the pump prime when I disable it, suppose it could be a different relay. You need to trace the wires back to the alarm box and connect them together to cut out the relay in the alarm. I occasionally get a similar problem on the starter circuit, it's done it twice now but has always fixed itself before I get a chance to fault find.

sigma m30 pin connections from http://www.mkivsupra.net/vbb/showthr...llation-Manual
1 - Blue - Interior light pin switches (neg)
2 - Blue/Red - Boot switch (neg)
3 - Green/Black - Low current programable output
4 - Green/Red - As above
5 - Black - Earth
6 - Black - Earth
7 - Orange - Ignition sense
8 - Red - 3a 12v
9 - Pink - Central locking (Configurable)
10 - Blue/White - As Above
11 - Black - Immobiliser circuit 1
12 - Black - Immobiliser circuit 1
13 - Black - Immobiliser circuit 2
14 - Black - Immobiliser circuit 2
15 - Red/Yellow - Indicator supply (15a)
16 - Yellow - Indicator output
17 - Yellow - Indicator output
18 - Green/Orange - Accessory output (neg during trigger)
19 - Green/White - Central locking (Configurable)
20 - Pink/Black - Central locking (Configurable)
in this example shorting / linking pins 11-12 and 13-14 would bypass the immobilizer.
Had to do this a long time ago for a friends RS turbo who's alarm had failed 1-2 was immobilizer circuit 1 (ignition) and 3-4 was immobilizer circuit 2 (fuel pump)
Depending on your alarm model it could be any pins you will need to find the wiring connections / diagram for your model determine which pins are the immobilizer circuits and short / link them out
