Okay, I took both covers back off, the crank turns pretty easily with a breaker bar on it, the oil pump, idler pulley, and tensioner all spin freely, and the distributor gears are fine.
No Idea why the new belt broke...
But I have put another new belt on and can turn the crank and both belts work great, but the car still will not start.
I was looking at the Haynes Repair Manual and it says after you install the driver side belt to rotate the engine one full revolution or 360 degrees then align the valve marks and install the passenger side belt, is this necessary/required, if so what does it do?
It is the only thing I hadn’t done previously.
