Fiat Fiorino does not reach the spark plug.

Greetings to all of the forum: I wait for their help, they brought me a Fiat Fiorino 1.5, well, this vehicle was transformed or carburetor put it therefore disconnected the wiring of the injectors.
According to the owner, but after a while I burn the ignition coil, they changed it and lasted two week to others changed the distributor and the rotor cover,
now, the module it has is a Magneti Marelli Mod.434m, Digiplex2.
The ignition coil has four pins and an exit to the distributor lid.
The problem that I have that does not reach the spark plugs therefore no part, when starting it note that the coil is a high temperature to the touch.
Therefore, it gives me the impression that the cables that reach the coil are not the one that corresponds, and are as follows: Pin 1 comes from the sheet, pin2 of a relay, pin 3 of the Pin11 module, direct pin4 to mass.
Someone from the forum can help me give a solution to this problem, of course. Carlos

They are only ideas, if it damages the coil could be a short circuit in the spark plugs, or problem with their cables, (high voltage leak). There are coils that require external resistance of very low value, or a special cable that does the same function is placed, so that it does not hot much. luck

Thanks Mechanica 5000; What happens is that I have no high voltage output in the coil, I get the impression that the cables that reach the coil (4) are poorly connected I have searched on the Internet and not found anything and I do not want to damage the coil since it is new, or it may be the module (Digiplex2 of Magneti Merelli) I do not know and I do not know how to check it. If you can help me I would appreciate it. Greetings Carlos.-
