@tomeighty: It takes Fuel and Spark to run an engine. Use this Spark Plug testing tool to quickly rule out one or the other when an engine won't fire off. Every Mechanics toolbox needs one of these. #sparkplugtester #sparkplug #mechanic #toolbox #tool
Well engine needs 3 things to run. Spark, fuel, and compression to run

I have 2 of these Spark Plug Testers, one in my Tool Box and one in my emergency kit in my truck. You can be a hero when you come across someone broken down on the side of the road and can figure out if the engine died because it wasn't getting Spark.

Fuel and spark to run an engine you say? I guess "air" does not play a part. What one probably refers to as the "Gas Pedal" has nothing to do with how much fuel goes into the engine either. It determines how much air mixture one is giving to the fuel. It's called the "Throttle Pedal." But hey, what do I know? One only needs fuel and a spark to run an engine. Right?
