Failure on

Good day. Let's see if you can support me. I have an Explorer 92 truck, which has been failing to turn on, I give the switch and give the march but it does not turn on, it does not reach the spark plugs, I already change the crankshaft sensor and check the ignition module (coil or pill) and tell me that it is fine, the problem is when it cool that it does not turn on (in the morning) New ... ignition nothing fails, it does not tremble or want to turn off ... I read in another forum a similar case and it seems that it was a relay, check those that are under the fuse box in the engine but stop that they are well, the same and I did not do it well, I do not know where you have the most relays. Can anyone help me ??? Thank you
