Not to beat a dead horse here (Gauge issues).
I jumped in my truck and started it up, all gauge lights (CE, Brake, etc.) came on as usual, then usually they all go out and you drive on as usual, but this time EVERYTHING went out.
Right after starting my RPM's went to 0 and all gauge lights stayed on (the truck was running fine though), then went out, then my RPM's went back to normal. But the Check engine light stayed on. I have a video of the problem if needed which is started immediately after everything went dark while the truck continued running.
About a week ago all of my gauge lights came on for a second or two while driving then went back to normal and I thought nothing of it. I've read around that this could be the ignition switch
