TFI module, EEC IV module, and the coil, in that order. Here is a link on how ot test each.
Also some auto parts stores will be able to test the components if you take them in.
Good luck and let us know. :)

Check the TFI module first, then the EEC-IV module, then the ignition coil. Some auto parts stores can test these components if you bring them in.
