If nothing is coming out of the coil it must be the coil itself or something earlier in the system than that.

As far as I was aware I thought the lights on the ecu should be going???? I could be wrong but there are no lights going at all on the ecu when the key is turned on!!! There is power to the starter motor and into the dash wiring all other lights are going just no lights going on the ecu..everything seems to be plugged in....this is probably also why the fuel pump isnt going Some original photos have not been recovered yet.

up behind the glovebox there is a ecu connector and on base models there should be a jumper in there. did you take it out?

Ignition wire was broken somewhere I think.....went into a plug and had a dead end......think it may have had something to do with the alarm that was pulled out......oh also i was stoaked it went....that engine has been sitting not running for 3 years and its had a 140km\h crash head on into a pole etc lol....and it runs like a dream.....sounds sik atm because it has no exhaust on it...straight off the turbo heaps of turbo whistle with excessive revs not that I tried of coarse :P Some original photos have not been recovered yet.
