Can bad points cause no spark?

Also question is, what can cause no spark?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Also Know, can a bad condenser cause weak spark? Weak spark is often the result of a bad condenser (and it's a cheap part to replace). If you see higher resistance here, then you need to clean and check the connections and the circuit path to ground through the points. Also check resistance between the distributor body and the engine block.
Also to know is, how do I fix no spark?
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.
Can a bad ground cause no spark?
backfiring through the intake is pretty much always firing order is wrong. Bad grounds can cause no spark issues though. It can cause the ground to ground through the ecu frying it. If you get a single spark when turning on the ignition then nothing when cranking it's the ecu.
