NEON 1996 Without spark

good to all.
I have a fault with a 1996 neon neon, 4 double camshaft cylinders, they brought it to me because they did not start since they changed their heads. So far I have checked the time and had it for machine 2.4 SELO corregi when turning the gear gears still did not come out spark of the coil. The crankshaft sensor is working correctly, the current arrives well and makes its respective current cut by moving the pulley so the current cut comes well to the computer. The coil works well because I put it on another neon and normally turns on. The computer sends current to the coil, but what checks in its cables is that what does not send is the signal to make the current cut to the coil. I thought it was the computer the problem, but when installing it in another neon it starts ...
so I could not diagnose this neon that na spark ... someone would know in their experience that defect could have ???
I will thank you very much. Thank you

Czech the camshaft sensor, verifies the synchronisation of camshafts with the crankshaft.
There is a relearning procedure for crankshaft sensors and camshaft. Greetings
