Can you give us a little background on what exactly you have and don't have? I know you've had a few threads of late and if we can tie all of the events together, that might help.
If only having no spark:
I'd put a test light biased across the electrical wires going to the coil. See if the test light flashes while cranking. If so, swap the coil.
If no test light flashing, confirm you have key-on 12 volts to the positive wire of the two electrical coil wires you just had the test light on.
If you have 12 volts to the positive coil wire, Check for injector pulsing. If you have inj pulsing and 12 volts to the coil, have the TFI tested.
If you have neither spark nor injector pulsing, the PIP is likely.
With more info, we can narrow down the testing pathways.
