i am new to the site and cant seem to figure out the problem, i have no reading on my fuel gauge, oil pressure gauge,temp gauge and voltage gauge. tach and mph gauge work fine. reading codes 920, 921, 999 from holding the odo reset button. any one have any ideas?

 

I've had this happen as well. Mine turned out to be loose connections from the input connection on the back of the cluster-a couple terminations were loose in the connector. I pushed them all back in and plugged it back in, then everything worked fine. I guess they just rattle loose over time? Might be something to check out on yours?

 

Ive seen a few go out like this and fixed it the same way. Literally just wiggled the connector and it came back on and never stopped working

 

Yea, tried that. Even changed the cluster out with another truck, did I mention I also have no charge coming froma brand new alternator and 2 brand new batteries. I ordered a PCM off eBay today. I am shore that is the problem
