87 Cabriolet starts intermittantly
 

Replaced timing belt, fuel pump, fuel filter, plugs, wires, cap, rotor, timed engine, new battery, cranks fine, just won't start most of time but when it does, it runs fine. Has good spark and fuel is coming in. will start fine after running. just cranks and cranks when cold or sitting for over 24 hours. what is going on? any ideas?

The ignition coil, might be bad.

Car runs fine when running, starts back up if shut off. Takes forever to start when cold. has spark and fuel. New fuel pump, plugs, wires, cap, rotor. What could be causing the hard starting. battery is also new.
