89 Ford LOST SPARK code said bad cam sensor-not problem

89 Ford t-bird lost spark . Have had an intermittent tach reading for a while. Code 14 indicated bad PIP or cam sensor wiring . Checked all harness wiring from that connector and replaced cam sensor to no avail. Wondering if a crank sensor or ingnition module ( glued to the compressor ) may be more likely. Would I get a code if Ign Mod failed?

Any body have a good guess , Help? Mike
