No ECM control of timing
Running the EBL flash. It isn't controlling the timing. The only timing I have is initial timing, with or without the bypass unplugged. When I do unplug the EST bypass, I get the CEL, and timing is still the initial at the distributor. With the EST plugged in, still get only the initial timing. Replaced the module, but nothing changed. Think it could be a bad pickup coil?

No, if it were a bad pickup coil it would not have spark.

The problem has been worked out. Don't get crazy with the initial timing.
