When you have a no spark situation the logical starting point would be the ignition system and work your way back from the obvious to the obscure. Not he other way around.

That rule of thumb applies to anything when problem solving.

When you have an AEM ECU that is known to be flakey vs. the possibility of multiple coils failing simultaneously I'm not sure which end is the more logical.

While your at it, buy a AEM series 2 or maybe a Haltech since you're an Ausie!

I got the laptop connected and it was finding sync so that eliminates that possibility. I then swapped coil 1 for one of my spares and on turning over it coughed and spluttered a bit. So I replaced coils 2 to 4 with my old spares and it started reasonably well. Guess it was a bit flooded from all the false starts.

Anyway the coils I had lying around were from my old motor and were a bit fire damaged and messed up but at least they start the car. Might shop now for soem newbies.

Thanks for all your help guys.

Glad you got it figured out.

why dont you diagnose it ......

I thought that was what I was doing.

Perhaps my lack of pace is confusing you. I do have a job.

step 3 in what i told you to do .... replace coils with good known................. I laid it out for you, it should haven taken 15 minutes ... so your job has nothing to do with anything ......................

I was honestly trying to help you... and I would have led you in the right direction instantly (being a veteran honda technician and all)

glad its fixed. now go shred some tires off !!!! hahah

As long as the coil drivers in the aem ecu dont burn out your next set of coils anytime soon.

An AEM EMS for the S2000 (1052 and 6052) isn't using coil "drivers" to fire the coils. The EMS in this application is simply sending a 0-5V falling edge trigger to the S2000 OEM coils that have built-in ignitors.

An end user commanding too much dwell (over charging the coil), higher than stock demands, increased engine bay temps, etc. are some of the factors that can contribute to coil failure.
