Dan,

You said this is a two-part problem. Maybe your new symptom is a broken
timing belt? Quickest way to check is to see if the rotor in the
distributor is turning while cranking engine (you might even want to do
it by hand for fear of valve / piston collision.

I don't see your mileage mentioned, but you're due for a new one just
because of the age anyway...
