Replaced Coil Still Get Light Any Ideas

Inspect all of the EEC connectors and perform a complete inspection of all pertinent wires and components to the coil/disto.

Check the profile ignition pickup (PIP) sensor. Pop the cap and push your fingernail down into the soft, gooey insulation surrounding the PIP sensor. This has historically been a red flag when hunting an ignition fault on Ford vehicles equipped with TFI ignition systems. The insulation around the PIP sensor breaks down prematurely - a condition that leads to shorting of the wires leading to the TFI ignition module. I have in the past replaced the PIP sensor along with a defective ignition module, if it has "soft" insulation.

Also, before buying a new one and replacing you may want to check the PIP and spark output wires to isolate exactly where you are losing signal to trigger the coil.

Check for exposed wires not just the coil wiring, check the entire ignition system and make sure to check the spark output wires.

These are just a few things. Hope it is of some help.
