Hi, got a new sort of generic coil (listed for this '85 Graduate) but when took off original and cleaned it, noticed the 'plug' was really still there. Installed new coil anyway, no change in symptoms which currently are:
1. Starts instantly and runs well when completely cold.
2. When I stop and start it say after running 5 minutes, it restarts fine, maybe even ten minutes restarts fine, but when temp needle gets up near middle to full operating temperature, and I stop and try to restart it, it does not restart, and THERE IS NO SPARK (as shown by neon bulb in series with plug wire.
Any ideas appreciated. Have had car for ten years or so and followed l jetronic checking instructions and checked or replaced practically everything mentioned in the l jetronic procedures.
Any ideas appreciated,
