Car will not start?

To test a spark plug you can just take one out and look at it while you try to crank the car. Be sure to hold it with something insulated or else the spark may get you. Harbor Freight also sells a little device that the spark plugs screws into, and then you put it in the spark plug well, and I think it lights up. I bought it when troubleshooting my son's Ford Ranger no start problem (turned out to be a g-force fuel cut off switch)

However, the wheel/notches that turns that the CPS looks at - does it come off during any part of the process? The reason I ask is that on the Miata that wheel does come off as part of a timing belt change and if you put it back on backwards you get RPM and spark plugs firing, but at the wrong times so the engine doesn't start. Flipping that wheel around and it started right up. I could be way off base. [Edit I just looked up some parts diagrams and it looks like I am way off base here ]

Good luck.

On the other, I went through the same thing in 2009 - it was a rough time filled with a lot of self doubt. There was no reconciliation and ultimately things got a lot better but it was a rough time. Best wishes.

The teeth are welded on or a permanent part of the DMF. The CPS never was moved or removed. I used a color inspection camera and checked the teeth.

Shot a bit of starting fluid in the TB. No kick at all. Has to be spark related. Car on the ground and just needs engine cover & access hole closed, and it's on the road. Just need some spark. Talk about self doubt!! I've examined the compartments and every single fuse.
