ECU failure 200 1991

the only ecu failure i have ever experienced was in a 92.
the check engine light came on, stayed on and when reset came back on immediately.

no codes were ever thrown when checked.

upon replacing the ecu the cel went out as normal.

i do know the PO had connected the tach wire to the cluster without a tach. besides frying the odo board this might have contributed tot he ecu problem although i have no way to know this

the car ran as normal with the bad ecu
