Car won't start after it ran hot due to cracked radiator

My son was driving his Nissan 240SX and it overheated due to a cracked radiator. We changed the radiator but it still won't start. Engine seems to be getting fire. Timing chain looks okay. Any ideas? I'm stumped

do a compression test, milky oil?

No milky oil. Checked it already.

You can have a bad HG without getting water in the oil.

If the radiator was cracked, there's NO WATER TO GET IN THE OIL.

You might want to take that radiator back and spend the money on a rebuild. KA's don't like to overheat.

Let's also educate the son on what the temp gauge means.
