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.

What could 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.

Can a bad ground cause no spark?

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 its the ecu. Its a really good idea to go over all your grounds on a regular basis anyway.
