IMHO, two different coils and no spark does not indicate to me that another coil is necessary to try, not without testing the two of them (and circuit wiring and coil and plug wires) and deeming the coils no good, but that something else is wrong. As "mrriggs" correctly pointed out above, a PIP (14) code does not automatically mean that a new PIP sensor will be the solution.
Code 14 (EEC-IV trouble codes begin bottom of the following image) from "CM" indicates the CIRCUIT has failed or is erratic, not just the sensor, but all wires and connections need verifying that they are okay too...
I'm going to start a new thread elsewhere with a bunch of sensor testing images and trouble code charts from my book, but will post what I hope is helpful for you in here.
I apologize for having come across in those ways. Absolutely not intended. I have been here a while and have seen the struggles you have had with your car, and honestly wish to try to help. People might wonder why I have contempt for these systems. I have good reason. I do not however have contempt for people having trouble or trying to make them work though.
Here are EGO/HEGO and TFI/PIP/SPOUT testing procedure page images:
Here is the wiring diagram (if not clearly visible, I'll try a larger image) that includes your car from the book:
Good luck with it.
