hello! bought this truck for cheap cuz it wont even light up the cluster let alone crank or show any codes... the previous owner changed the pdm but not the fcm... i havent tried to read through the obd2 port but im sure its no comunication like every other thread ive read!

what are my options? does anyone have a link to the factory service manual? where do i check for power? someone mentioned fuseable links maybe? i know its got power to the PDM and the blower works well.. the radio was working but not anymore!!

where do i start!?!

 

I had that happen and it was the fuse for the ignition blown. Replaced it and everything was working again.
