Man, the key in the dump truck would not turn to acc at all. You have to pull the key switch out and on the bottom end there is gear with 3 or 4 teeth that match the 3 or 4 teeth down in the hole the switch came out of. Reach in there with a flat blade screw driver and move that gear tooth forward a click, make sure the key is in the same position when it was removed, then slide it back in.
Sometimes there is a problem with the switch down on the column where the wires plug in. Is the the switch that you replaced recently?

Yeah, but understand that I'm not there. So you may have to move it the other way, it's been an minute, You're synchronizing the key to the switch on the lower part of the column. There is the gear that pushes/pulls a piece of linkage that moves the internal part in the electrical switch.
This is exactly how I did the truck: (basically the same key start system) moved the gear in the column till the started engaged, released it so it was in the run position like you weere gonna drive away. Inserted the key switch in the run position, turned key to off, then lock, then acc to make sure it was in the right position, turn key to start and it worked, everything is fine now.
Did I get lucky?
Likely yes.
I called it a win.

Try to get us a pic of the bottom of the key cylinder and the hole it goes into.

So I figure you have not taken that snap ring off, so the gears are not exposed but you still should be able to turn the mechanism with a screw driver in the kinda square opening and turn it to start, the key cylinder will likely only slid in two positions opposite each other,
I believe your next move is to inspect the switch under the dash on the column, look for the rod that pushes/pulls the switch mechanism, turn the key, does it move?
Is the connector to the switch tightly plugged in? See any burnt marks?
You will likely need scruity torks bits, local parts store have them really cheap, you'll see what I mean when you see the screw heads securing the switch to the column.
I'm thinking switch issue?
