Hello MRicho,

Retrace your steps, make sure everything is tight and the connections are snug. It could be that you must have of missed plugging something in. Check the spark plug boots, coil packs and make sure its all in there.

How much water was present in the hole of the plug, was it just one hole that had water or were they all like that?

If none of that works, scanning the car would be your next step.

What did you try to do, wash the engine ?.. If there was any kind of moisture in or on plugs, boots, plug well.. You've "carbon arced" some or all of the above.. Look for tiny, thin black lines on everything.. You either have to grind ALL the carbon off, or replace the part..

If you're going to wash your engine, then it's a really good idea to start that engine up first, then immediately do the wash before it gets really warm.

Your crankshaft position sensor is right at the top of your transmission bellhousing. I'd scan the car, and if you're seeing a problem with the CPS, then go ahead and change it.

Any sort of position sensor that has faulted can cause a crank but no start problem. It could be possible though that it could also cause a no crank no start.

I’ve included a link to an online Starfinder resource. Starfinder is the dealer software that shows all of the wiring diagrams, fuses, etc with photos.

I wish that I could help you more, It seems like you got water on a lot of the electronics.

Get a hair drier and blow-dry every cable and connection under the hood that may (or may not) have water on it. Go out when it is dark at night and crank the engine (Will need two people) and look for any sparks.
