As above i have a s13 CA18DET that im taking to stage 3 with all the required mods, i have installed it all in the car and then tried to start it. Originally it tried to fire but then died and then came a clicking sound from the engine bay, found the clicking to be coming from the injectors the ignition amplifier and the air con relay. i have narrowed it down to an ecu fault so i have sourced another ecu and installed the chip into that, now when i turn the ignition on the clicking has gone but im getting no spark upon cranking. any advise on where to go next? im wondering wether the clicking saga has killed the ignition amplifier? i have checked all the engine bay fuses and they are good.
