Question about 1995 Mitsubishi Montero
Hi, all 3 coils are powered by the black wire from the ignition switch (12 volts). The ECU pins providing the timing signals are shown in the diagram below. Check to make sure all 3 coils are getting power, then check continuity of the wires from the power transistor and on to the ECU. Please let me know if you have more questions, and thanks for using FixYa.

Usually,if a coil is bad,it's bad.your coil pack for the following cyliders may have blown. or simply went bad.it does happen,but not often,you may simply need to replace the other 2 coil packs to repair your issue. try interchanging the good coil with the bad coil to see if it fires,if it does,then you have bad coil packs.stranger things have happened. trust me.are you able to have it code read? if so,what codes do you see?if this is no assistance,please repost your question to fixya.com and thank you for choosing fixya.com

Please see my tip at http://www.fixya.com/cars/r6223989-ignition_coil_doesn_t_spark . These are generic instructions--specific instructions are pasted below from Autozone.com. If you get stuck, please get back to me.
Use a test light to check for power to the coil on the black wire with a yellow stripe--see procedure below and other tests you can run. You will need a volt-ohm meter to run most of these tests.
The system used on 1990-95 Accords and 1989-95 fuel injected Preludes uses the distributor components to signal the engine computer. The ECU triggers the spark through the igniter unit and coil. This spark timing is controlled by the computer as an integrated function of the fuel management system. The distributor contains a crankshaft angle sensor and a No. 1 Cylinder Top Dead Center (TDC) sensor. Using these and other electrical inputs, the computer controls spark timing electrically.
