Before I start, I'd like to thank you for the advice on the MAP sensor problem.

Now its a no spark in the leading coils. I tested the coils by removing each spark plug and using a new spark plug to a ground point. Trailing coils spark, but not the leading ones. When I turn the "key on", I will get one arc on the leading, but during cranking, no spark.

I haven't tried restabbing the CAS yet, but didn't think I had to because it was untouched. Engine is a 13B-RE Cosmo in a S5 TurboII.

I'm thinking its my Haltech settings that I may have wrong. Can anyone check?

So what do you guys think?

Are you using the stock coils and igniters? if so, are you using the toggle feature and setting the trailings through digital1 and aux.out for the toggle select? Also, are you primary coils getting proper 12V power?

Have you tried just setting everything to standard mode just to see if Ign.out is working? if not, it might mean that you need to ship it to Haltech to check it.

yes, I setup the ignition as you did in this thread:

Yes, the leading coil is receiving 12V because I will get a single arc with the "KEY ON" position.

The trailing coils are firing fine.

Oh, yeah, that is an old post, the reason for my troubles was that the toggle check box isnt selected with rotary mode, that is for 4 cylinder toggle mode so you can wasted spark and sequencial fuel, the toggle is selected in the Aux.Out wire, so that is wired up to the toggle switch on the trailing coil igniter, and Ign2 goes to T1, BUT! sometimes, some people have reported (including me) that on some X boxes, the trailings are back to front. You need to check the Trailing plugs with the timing light to make sure T1 is at 20 deg ATDC and T2 is 180 degrees out, if they are backwards you need to swap coil wires.

Try that, reset the ECU properly, and see what happens, sometimes the X needs to be properly reset to apply the changes, i always hit enter on all things i change, AND "apply" twice to make absolutely sure its been applied.

Sorry for digging up an old thread, but I'm having the same issues with E6X.
When i turn the key to on position my rpm gauge would tick (like original post said getting a spark on ON position)
but when it comes to cranking I get no spark.
Car was running fine few days ago till I had fuel issues, tried to resolve that problem by tracing wires back to the E6X ecu. Now that I got that sorted I lost spark which is really confusing.
would this be CAS wiring issues?? or Ignition wiring issues? anyone have an idea what to keep an eye out for what wiring I possibly touched and messed up?
