   So there isn't a flashing orange key on the dash?
   
   Also when I did my conversion, I put 2 earth's onto the gearbox, and 1 to the chassis - and that caused mine not to spark. Should have 2 on the chassis and 1 one the gearbox.
   
   Worth a try..

   So what ECU are you using? And what have you done with the immobiliser box under the dash, exactly?

    Crank sensor plugged in properly as this is what sends a signal to coil pack?

    Yh I checked them well the alternator, gear box, coil pack, under manifold, the one that goes into fuse box and the other one that goes to the bigger fueses and the one that goes to the chasi behind battery.
    Is there any I'm missing?

    Is there 2 on the chassis and one on the gearbox?
    
    Might sound daft.. but when I had 2 on the gearbox and 1 on the chassis it wouldn't start / had no spark
    
    Swapped them over and it fired.. and it's ran since

    no spark or no fuel?
    you immobliser cuts the fuel supply not the spark so theres no point unpluggong your immobliser if your getting fuel....

    Do you have any spares like coil packs/crank sensors that you can swap over?

    How are you checking for a spark? Holding the coil pack in mid-air won't give you a spark afaik.

    So you aren't using a properly unlocked ecu then by the sounds?
    
    Locked ecu = no spark
    
    Unplugging the immob box only works to unlock an ecu Whilst the engine is running.. And if it gets put on another car with the immobiliser box still in it will re-lock.
    
    So you sure it's been unlocked professionally? Most professionals remove one pin to completely eliminate it being able to re-lock.

    Your immobiliser on a saxo cuts the power to the electric FUEL pump,thus stopping the fuel from getting through.

    My conversion wouldn't start because I had bad earths and no fuel getting to the rail, simple things are often the cause. U need to earth the plugs when checking for spark,

    So how did a coversion i completeds pump prime with a locked ecu? Surely if it infact did that the pump wouldn't even prime?
    Curiosity.

    A locked ECU MM IAP.41 which i guess your using a single plug vts ecu will still prime the pump for 2 seconds on 2nd click. They also turn the fuel relay on manifold heater etc.. But then shut off and won't spark.

    i bought a unlocked ecu off here, which i thought was the problem then was disapointed when tried to start it, there is fuel just no spark

    Okay I'll do that.. To the opticians or school for you I take it?
    
    Also cam was the helpful one and actually answered my query. As it appeared you didn't have a clue..
    
    Any conversions I've done get fuel and no spark if the immobiliser is locked.
    Granted they were 106's but they have the same part numbers on the immobiliser boxes etc so I assume the system would infact work the same?
    
    Either way mine would fire fuel out of the injectors when first trying to crank over but would not spark.
    
    Thus my original post.
