Hi. It sounds to me that your fuel pump has seized. Speaking from the electrical experience, the reason why wires were burned is because the pump was pulling way to many amps from the battery. Usually that happens if the motor or a fuel pump in this case struggles to turn around until it seizes. What surprised me was that the fuse didn't blew first. You need to inspect the fuel pump and probably swop it with a new/working one.

Thank you, i will check the fuses and the pump relay, maybe they burn out to. Have any idea of the ligths? They run in a secuence, not really sure of the order but is about 37 pulses per cycle
