Hi All,

As above I am after some urgent help. My impreza has died and has the classic sigma immobiliser fault. Pump not coming on, all relays and fuses etc checked and all ok.

Could someone please pm me the location of the immobiliser and what I need to do to bypass the fuel pump.

Would really appreciate it sooner the better as I have had to leave the car in a vulnerable location.

Many Thanks,

Nigel

 

You checked the wiring under the back seat ?

 

Hi Yes have checked under the back seat and all ok. Hopefully someone can help me out.

 

I doubt anyone would tell you how to get round it in a open forum.

 

I had thought of that just hoped on the off chance someone might know and pm me before I spend a fortune.

 

sounds daft have you tried moving the car a short distance to see if it is lock out due to interference ?

 

I have moved it from the main road it broke on to a side road, approx 1/2 mile so I would say I have eliminated that.

 

Search on here through my posts I told someone recently how to bypass the fuel pump immobiliser circuit and the rest of immobiliser remains intact. The relay for the immobiliser fuel pump circuit is fried and unable to be replaced as it's in the immobiliser unit so the only option is to bridge it and splice the pump wiring back to std

 

Had a Similar problem and ended being the ignition live had failed so ran another wire to the ecu and all was fine again
