Town country 97 doesn't spark

That such friends ask for your support to start my town country 97 engine 3.3 truck which does not spark at the spark plugs I was checking and apparently there is also no voltage supply in the coil I clarify that I am not a mechanic but if I am an electronics technician so that I have a tool to be able to take out this fault, what I need is to know the check procedure where the voltage that feeds the coil or a diagram comes from and how to check the associated components, thanks in advance for your contributions

first check if you have a positive voltage when you turn on the key, check the negative pulse when starting if you don't have a negative pulse, check the crankshaft sensor

I already checked the diagram I do not have voltage on the green cable with orange that feeds the coil module if I have negative pulses but the 12 volts are missing but I do not find that relay provides these 12 volts I do not have the cover of the relay positions I would appreciate if you tell me what it is

The relay is the automatic design SHUT DOWN RELAY when the switch is opened. This relay is activated for 2 seconds, once it goes over the currents, it reaches the relay in the first diagram, the currents and fuses that feed them are fused. feed this relay and find itself in that fuse and relay holder
