    No power to fuel pump or spark? Not a nats problem.

    I have removed the nats out the question thanks to some peoples help, this needed done since I didn't have a halo or the fob for the car. However, now that I've got round nats, there is still no power to the fuel pump or any spark? Any idea's, all fuses seem ok. Will take a multimeter to the car tomorrow.

    I found some suspect attempts at wiring just in behind the connector for the ecu. How hard is it to replace the interior/under dash loom?

    Yeah I probably could, but it would mean tracing all the wires to check what they are before I strip them out. I just thought it would be easier to replace the loom.

    Looks like someone's had a real go at it, lots of cut and joined wires wrapped in tape, and wires coming from elsewhere tapping into the wires on the ecu.

    Our S15 was like that a lot of imports are I've ben told rather than or its had timers or safc fitted in the past.

    sound like you might be better to have a bit of a sort out and rewire.

    All the wiring and pins are in the useful s14 thread at the top of the s14 tech sub

    just make sure you remember where your after market bits tapped into.

    does the pump prime initially when you turn on the key?
