hey greg, dont buy a loom just yet have a look at my posts and go through the wiring on the ecu there is a full check list. its dead easy or even better get hold ov an led tester and plug it in to the ecu they more or less point you to the right directin.

what i done was check that you are getting power to your ecu, if you are then now check you are getting an ac voltage back to you ecu from your crank and phase sensor, just cos your not getting a spark it doesnt mean its the sensor,

unplug the ecu loom and unplug the phase an crank sensor, if you have a metre check that these wires are not broke,. i will put my house on it that its a bad earth dis connect all the engine earths and clean them up.

check from batt earth to ecu pin 1 i think that there is a good 10 ohms if its less then the cable is damaged or a faulty connection..

pm me ur number if you want...am better talkin lol
