N15 immobiliser/fuelling problem

Hello i bought an almera sri to use as a banger car fully stripped it out but as i was doing the wiring i accidentally snapped the wire going to the pickup ring around the barrel. So the immobiliser kicked in and stopped the engine from starting. So i took the fuel pump out submerged it in a tub of petrol and hardwired it straight to the battery, i checked it sparked which it did so i connected the fuel pump to the fuel rail and it started but only for a few seconds then died. When i spray aerosol down the throttle body the engine stays alive for much longer so i thought it could be the injectors checked all the connections there all putting out 12v until i crank the engine then they all go down to 8v. So removed the fuel rail cranked the engine over and nothing was coming out of the injectors. Can anyone help with telling me the next step or by explaining the problem. I have tried looking for a new ecu transponder and key but cant find any with any similar numbers.

Cheers and thanks for any help!
 
Sounds like when you snapped the pick up wire its activated the fuel cut system have you tired patching the pick up wire back to normal, or try taking a look at the FSM?

I did try yes but the wires came off the circuit board i tried soldering them back on but it didn't work. Not quite sure what FSM is?
The pickup rings aren't car specific so you should be able to just replace it.
Oh really thats good news thought they were all coded together cheers man i will try and find one.
 
Lol sorry factory service manual if not send me your email address and I'll mail you the pdf manual mate
