Gentlemen:

My '96 Imprezza ran like a champ despite 500,000K on the odometer...then the timing belt came apart while I was driving; "Whizzz..." was the sound I heard when it did.

SOHC non-interference EJ22 engine. A new timing belt (and water pump) was installed three separate times; each time, the engine starts and runs...but once the radiator is connected and everything is in place, the engine turns but won't start.

About to buy a new engine, but don't even know where to shop around for one.  I feel in my gut something's being overlooked. What could it be?  Please help -- I'm in North Central Florida and trying to get it operational before our nation collapses. Thank you and God bless. 

So when it starts and runs, how long are you running it?

I take it very short since there is no coolant as the radiator is out?

Radiator in, filled with coolant, and no start, is that the case?

www.car-part.com will let you search for an engine.  If it was running well before the belt broke, I would not give up on the engine yet.

What caused the belt to break?
