It's a sport model I think. 4.0L I6 engine, automatic.
Starter is good, battery is good, cranks over fine but doesn't fire.
Checked the valve on the fuel rail and seems to have pressure, and builds up pressure again when turning the key off and back on.

I see that the coil packs are a one piece unit so not sure how to check for spark.
I tried unplugging the crank position sensor and plugging it back in, but no change.

Any known common issues to look at?
