To test a 1991 Ford F-250 ECM (Engine Control Module), start by checking for any diagnostic trouble codes (DTCs) using an OBD-I scanner or a code reader compatible with that model. Inspect the ECM connectors and wiring for corrosion, damage, or loose connections. You can also perform a voltage and ground test at the ECM to ensure it’s receiving the correct electrical signals. Finally, if necessary, you can bench test the ECM with specialized equipment or consult a professional if issues persist.
