The TFI should be located on a Aluminum heat sink on the radiator support. Other than the PCM, there is noting else in the ignition system.
If it misses all the time, an easy way to check ignition function is to put a timing light on the Coil wire an see if there is any interruption in the light when it misses. If there is, it is the TFI or Hall sensor (Pickup coil).
If it is not ignition, one other thing I have seen is a corroded wire at the connection between the Injector harness and the Main engine harness.
Keep us posted.
