Friend of theme "There is no spark", so little that can be seen in your message, I see that you have no ignition, and the possible reasons are: 1 Verify that you have 12 volts in the food of the coil, if you disconnect it, in one of the two cables that reach it, there must be 12 volts. 2 If you have 12 volts, verify that the La Gatille module, with an analogous Ampouletita flashes, suspicion of the bad coil and change it.4 If you have no sign or flicker You can but it is done with oscilloscope, and the signals are very weak and you have to have habit to measure it with a tester. 6 If there is no injection, you can suspect the signal collector, or in some low probability the computer. These units alone do not fail, they always do it for third -party effects.7 The module if it has it external, you can identify the input signal, and see that the computer signal is reaching the module, in some of three pins, they function as a power transistor, which makes a PIN Temperature dissipator. In other modules of more pins, they have a pin with 12 volts, one with negative, one with a computer signal, another with the advance signal, another with the coil trigger, those are a bit more difficult to measure, but with the advice of a technician in electronics you can verify it. The same if you can get another one, you install it and tests, which would be the easiest. If it is switched inside the computer, that requires the technical hand, to measure components, which one must know very well to determine that it is. Perhaps if you send the complete data of the car, such as motor number, cylindrated year, brand and model, you can make a more detailed tutorial and be successful in your repair. Greetings for while and luck. Valdivian.
