Mazda CX-7 won't start...Help!

[mazcx72010]

I have a Mazda CX-7 2010. It overheated, blew the radiator and I got a new radiator put in, still won't start, makes a whining noise. Another guy said it's cranking but won't start and he can't figure out why, any ideas? Please help!

Compression test, most likely followed by a leak down test.
