Rebuild the computer? Interesting. Let me know how that goes.

Did you measure voltage between +B and E2, or the ECU +12 volts to ECU ground? That's important.

Also - When you turn on the key the check light shouldn't STAY on, but it should come on for a second or so. If you can get it to come on LATER, that means the circuit and light bulb themselves are good.

This does sound like a bad ECU. You can get a used ECU for MUCH LESS than $290! Check out the used forums. ECUs aren't usually something that break.
