I have a 2002 mercury mountaineer v6 4.0L. I'm having a start up issue. I have replaced the starter and battery is at full charge. I have power, but no spark to the engine. I turn the key and nothing happens. Wondering if its the distributor or spark plugs. Was having slight starting issues before hand

You need to check for power to the little wire at the starter when the motor is cranking to verify if there is a supply issue of electric or a bad starter

I replaced the little wire as well. I was told fords/mercury are known for bad wiring connectors so I went back and replaced that.

I had no reading. Tried several different grounding spots. So i'm thinking it's the ignition switch.

Starts at the ignition switch and goes through the park neutral switch.

Check each for power before throwing parts at it.

Good afternoon,

https://www.2carpros.com/articles/car-cranks-but-wont-start

Check this guide and see if you can give me any more information. You need to check for fuel and spark to see which system is not working.
