Brand new distributor. Brand new coil. But I cannot get an RPM signal to the ECM. Tried also replacing ignition control module and still no spark.

Hi,

The code is a transmission code related to the 1-2 shift solenoid, so that isn't related. As far as the no-spark issue, are you getting power to the coil? There should be a pink wire from the ignition switch providing power with the key in the start or run position. See pic below. Check that and let me know if power is present.

Let me know.
