Good read here on troubleshooting TFI system: Ford EEC-IV/TFI-IV Electronic Engine Control Troubleshooting

Print the worksheet

As a quick test you can hook up a jumper wire from battery + to the coil + then crank and see if it starts.

TFI can have a run wire and start wire, if start wire is the problem coil will have no voltage when cranking, only when key is in RUN position, so no spark when cranking
