Re: No fuel or spark

What is the vehicle? You can go to the autozone website and get the wiring diagrams, How about the fuses and ignition switch?

Re: No fuel or spark

Those wires are powerd by the PCM power relay. In the battery box, fuse 11 triggers it and then fuse 41 feeds power to those wires.
