Electric problem does not reach a spark to two mitsubishi galant coils year 94

Hello good night, if someone could help me or advise what I should do. I have a mitsubishi galant that I bought with an electrical problem, the car did not reach the spark to the coils, it sent you to check the computer and they tell me that it is perfect, so it sends you to change the crankshaft censor, ignition module, they already tested the individual coils and all are good I do not understand why the signal sends the signal to the coils, but only the one in the middle is the one. Igal the medium is the one who mandates spark, I do not know what to do or where to review .If someone has had the same problem I would thank you to help me to solve it thanks in advance who can help me.
