Thanks for your input Robert.
If you re-read my post though, you'll see that I
tested 7 of 10 cylinders (to ensure I was seeing both coil packs), but did not say that I'm only getting spark on 3 of 10 cylinders.
In actuality, I am getting ZERO spark on any cylinders. Were I getting spark to a few cylinders, I'd probably have solved this by now.
Also, I've completely bypassed the AEM and tried running on the factory ECU with the same results.
That said, aside from the spark plug wires, there were no non-factory components or wiring left in the system during that test. Trust that my first thoughts when something isn't working properly is that it's something that's been modded. That's why I eliminated everything outside of the factory setup.
My understanding of the ignition system is that it will not work without both good cam and crank trigger signals. The ECU needs to see the cam signal to initiate the ignition sequence,
then the crank trigger signal is used to maintain ignition timing. If I install a new cam sensor, aside from coil packs it appears to be the last component in question. I just don't think both coil packs would give up the ghost at the same time.
So, if a new cam sensor doesn't fix the problem,
I'm gonna give up and hand it over to my tuner. Because at that point, it will be beyond me. It will take someone who is knowledgeable enough with the engine harness that they can identify the right wires, and know what voltages and signals should be present. I'm not stupid, electrically speaking, but this will call for someone with knowledge and ability that I lack.
..and we'd start be throwing the VEC out, and getting a Pectel!
