Why is my no spark tester not turning on?

If the tester stays OFF while cranking, there are 3 possibilities: Points shorted (stuck closed). Condensor shorted. Coil open. Take the Green points wire off the coil terminal. If the tester now goes ON , either the points or the condensor is shorted. Replace both. If removing the Green wire still did not turn the tester ON , the coil may be open.

How can I tell if a distributor has been replaced?

Assuming you are replacing the distributor, take out the hold-down clamp that keeps it in place. Some of these are hard to see, but locate it and remove the clamp and hardware. There’s no reason to mark the old distributor since it won’t be going back in. Now compare the new (or rebuilt) distributor with the old one.

@ahughes05 if you are 100% sure you have no power reaching the spark plugs you need to check the wiring to the coil, the distributor cap, carbon brush and the rotor arm. That is probably what you are referring to when you say ” contact breaker”. If all that checks out normal the fault is probable with one of the system sensors.

Why is there no spark from the ignition coil?

Its like the ignition coil is not collapsing to send the spark energy to the spark plugs.
