For some reason can't find your other post in my gmail.

The coolant temp sensor used by the ISV module is also used by the
ECU. On my 2.1 it's located in the driver side of thermostat lower
housing. Not saying this is your issue, but IIRC, you had commented in
another post about this part.

It's easy to measure the resistance at the ECU connector.
