My car isnt running and wont start so the Ecu is my last option for diagnosing.I opened up the ecu and saw no capicitors leaking, can an ecu be "done" or "toast" with no signs of anything burning or anything leaking?????

my 1jz wouldn't some start some times, it was the coolant temp sensors, there's two sensors in the front of the motor one for the ecu and one for the gauge i think, the one for the ecu was working randomly so it wouldn't start sometimes.

When you turn your ignition key to "ACC" just before you start and all the warning lights are illuminated on the dash, do you see the check engine light? If not then you have a problem with your brain. Make sure you are getting voltage to the brain especially the black and red wire that comes from the main relay.
