Good Evening all,

I am currently trying to diagnose a spark issue with my 1984 Crown with the 5ME. If anybody could kindly steer me towards an ECU - Ignition wiring diagram or complete workshop repair manual, that would be greatly appreciated. It seems a previous owner has had a fairly good hack at the loom, installing an old Cobra alarm system . Now the poor old girl has zero spark at all and the coil, leads, and plugs are all brand new. Any help would be greatly appreciated.

If all else fails, I do have a 1UZFE and A340 with a loom I might put in it, but repairing the 5ME would be the most cost-effective and easiest.

Thank you.
