Ford Ranger ignition system 2.3l 8 spark plug

Hello, how I tell you I have a 1990 Ford Ranger truck 2.3L 4 STD cylinders of 8 spark plugs with ignition system, the problem is that it does not turn on, check gasoline pressure, pulses in the injectors, Crank sensor, DIS module, coils, compression in the cylinders, spark, etc Computer currents (EEC IV) and all good what he noticed was that when he marching sometimes he gave explosions as if he were out of time this made me check when he gave the spark and that is the problem "the progress of time is very advanced or backward" since it gives the spark at the wrong time, when seeing this it takes away the bridge of the spout signal because if you take this timing you do not 10 ° And it was in fact that he wanted to start but still a print that carries the truck says that in order to turn on the engine must be previously heated; My question is as follows: The problem of time progress is handled by the ECU or the DIS module ??? What can I do or recommend to start my truck?
Greetings I hope you can help me

If you remove the spout, the ignition is delayed.
The variation of the advance to the ignition is managed by the ECU.
The Mòdiculo DIS acts as an amplifier of the high tension generating not only a greater amount of spark but also more time of presence of the same, thus optimizing the combustion.
I think you could have the time band out of synchronization.
I leave you a band scheme so you can control it
