When the gauges don’t come on & it doesn’t start, do you mean the starter cranks the engine but it won’t start or you get nothing from the starter at all?
Also when this happens check 2 things, does the radio & heater fan come on if you have them turned on? If yes to this then go to the fuse block behind the glove box, find fuse 11 & see if it has power (12v). Do this by pulling the fuse & checking both terminals in the socket with a meter or test light. One of the 2 should have power (12v). Do all of this when the key is “on” & the gauges (cluster) are dead.
If the engine cranks but won’t start, the gauges are dead & fuse 11 has no power then the ignition switch is probably bad. Also the fact that you can get it going by turning the key a few times & eventually it works indicates a bad switch.
If you do need a new switch, there is a video of replacing the ignition switch here. It is about replacing the actuator pin but the switch is removed as part of that repair. You will need a t10 security bit or you can break the security pins out with a small punch & get it with a standard t10. Also look at the actuator pin, they are known to break, you might consider replacing it when you have it apart.
