If you removed your distributor, it's possible the rotor is now facing the wrong direction. Easiest way to fix that is to take the spark plug out of cylinder one, and put a dowel rod inside. Turn the engine slowly until the dowel rod is at its highest, that's TDC, and where the rotor is facing is where you start plugging in wires. Of course, then you'll need to adjust timing with a light. That gave me quite a stink when I rebuilt mine... I didn't realize that the rotor could even get misaligned.
That may or may not be your issue, but hopefully it helps!
