If I understand you correctly, the engine is not turning at all....period. You turn the key even after you have replaced all those things - the lights come on but the engine just sits there in silence.
Remove the spark plugs and connect a socket onto the crankshaft and see if the engine turns or it is frozen.
If it does not turn at all - then my guess is when the hose blew, all the anti-freeze came out and the engine overheated and seized up.
I have also attached the testing of the ignition switch....if the test comes out okay then you might try what I have below to confirm the engine is frozen. I also attached replacement of the ignition switch.
If it does rotate, then see if you can't connect a jumper cable directly to the positive lead on the starter. As you already know since you work on cars that is a HOT wire now. So make sure it doesn't ground on anything to spark. Next take the other end and touch the positive side of the battery. Does the starter try to engage but can't turn the flywheel? Has it engaged the flywheel and is stuck in it because it can't turn it?
Then again, to me you have bypassed all items in the ignition and went directly from the battery to the starter - the same as a bench check on the starter. Which again indicates the engine is froze.
