lost my gauges tonight? and my lift pump, and idk>?

No bus in the cluster is pcm related most the time. I know its been said check the 2 big grounds that plug into the passenger battery.The ecm regulates charging and gauges. I would swap relays around with the loud clicking. Also a bad ecm will cause a wait to start light to flash most of time. Can you look at it with a scanner and communicate with the ecm or pcm? Also check the ground on the drivers side of the motor near the ecm plug.

I did figure out that the clicking noise i hear is the a/c clutch everytime i turn on the key. Never did that before and im certain the pcm is causing it to do that. Im prolly going to break down and haul it to a garage. First time in my life! I tried another pcm but it didnt work out becuase we werent sure what year or trans it was for. Thanks

Figured my truck out today! Hooked up to my uncles snapon scanner and had no communication at all. Checked underhood fuses and the 20 amp for engine control #1 was bad. Replaced it and now everything works. I checked months ago and was sure they were all good fuses. Maybe its just a coincidence and only temporarily fixed my problem?
