this truck has sit for a year and I went to start it up -there is no spark+there is no lights or guages working on dash+even the signal lights on dash will not blink on dash even if you put on the 4 ways +
starter works fine.

 

Could be dirty battery cables, a blown fusible link or even a wire corroded off from sitting over time. Look at wire ends on the solenoid, and check around for loose wire or a blown fuse.
