Gday fellas finally made an account here, I've got a Xh xr6 just installed an au bottom end with an el tickford head stage 3 crow cam, and gtx 3582 into my Xh, the ute was running fine without the alternator connected just off the battery, I have since changed the alternator, and with it hooked up or not it will not fire, the timing is the same as when running injectors are pulsing theres adequate fuel pressure, and spark seems okay but it will not start or fire now, interior light fuse is fine, could my coil have just s**t itself and to weak a spark under compression? New dizzy, tfi module, the coils not that old and still has spark I'm lost here and have searched everywhere thanks
