How to test ECU?

[silver98bullitt]

I have a problem with my ECU in my recently 1uz swapped 4Runner. I have ran the engine in the truck but not driven it yet. It ran fine the other night in the shop then I cut it off. I let my cousin borrow my battery to crank the racecar and after hooking the battery back up the next day in my truck, all I get is the engine turning over but no start. I'm kinda leaning towards a fried ECU, but I want to make sure before I buy a new ECU. The check engine light use to come on when switching the key to the on position and then cut off after a few seconds like it should. Now, the check engine light never comes on to say that the ecu is powered up. Anyone have any idea how to check the ecu or test it to see if it is coming on? My engine and wiring are from '91, I'm not sure about my ECU. The part number is 89661-50030 and has the 26 22 16 26 pin configuration.
Thanks for any help

Unlikely its a fried ecu, they are a very rare occurance.

Start by making sure you are getting +12v at the ecu where it should be, check the fuses, grounds etc.
