So, yet another update...
Fitted new ecu, as excited as a kid in a sweet shop. Connected everything else back up, key in, turned over a few times, wouldn't fire up. Unplugged the king lead to see if it was sparking, nope.
Reverted to the igniter test using the light tester with ignition on, nothing... Removed key, it sparked nice and strong. Not a clue what that's about as the instructions clearly state ignition on. But still, that leads me to believe the igniter and coil are fine and otherwise would work as they should. Next I did a quick error code check, and code 14 is the one I'm getting.
I also disconnected my clifford just for the sake of ensuring it wasn't causing any problems.
So, I've now replaced every part possible including ecu that could be causing my no spark issue except key and barrel. I don't know what else there could possibly be.
I'm really holding myself back from picking up the sledgehammer :-(
