I couldn't find anything wrong with my ECU, but maybe I missed something. Pics are high-res.

Anybody See anything wrong with my 1J ECU?

Take a good look at the caps. I believe there are 5 of them. Also even though they don't appear to be leaking out they could still be leaking. I sent my ecu to Aaron and from my eye there was nothing leaking but the values were messed on a few.
Which ones are the caps? I don't know anything about circuit boards. Only that they are green and silver and have different colors :biglaugh:

They are the black things that look like tiny batteries and have 2 prongs going into the board. Its super common for them to wear out because they only have a limited life. Sounds like what happened to your car happened to mine. Hopefully you can find another ecu to test but I am pretty sure that is your problem.
You can check if your ignitor works by pulling out a plug and checking for spark. Are you getting fuel as well?
As 10secdream said, if the capacitors look fine it doesn't mean anything. Their values also can't be measured while they are soldered to the circuit board, so your best bet is to send it to driftmotion or someone who knows electronics if there is any question that they are good or not.
I just checked the igniter with a brand new one and I still have the same issue. I am getting fuel (as confrirmed by my FPR, and hearing the fuel pump whine, as well as cracking the fuel line open just before it goes into the motor and cranking it). I've already ordered a 1J ECU that I found on Egay, should be here tomorrow or Friday.

Personally I would have just got Aaron to replace your caps because even on that used ECU off ebay the caps have probably not been replaced and can cause the same issue again.

Well you should still send it to Aaron anyways because you can get it fixed and just sell that one when your done with it.
Best of luck, I hope it fixes the problem.
