Yj won't start after engine rebuild

I rebuilt my 2.5 liter and now I can't get it to start. It would run before rebuild but had lots of blow by due to a hole in number for piston. This is the first jeep rebuild I done so I took lots of pics to ensure the assembly. Any recommendations?

Start with the basics. Make sure you have fuel getting to the engine. You can pour a small amount into the intake and see if it tries to start. If so, you have spark, and no fuel. Verify voltage to the coil, check CPS connection, as well as the other sensors.

I think the timing is off some how I set it just as the book said but I rotated the plug wires on the cap counter clockwise a quarter turn and got it to fire and run but was holding throttle half open and it ran really rough. I guess I will take down and start overon the timing. Any little tricks to ensuring timing is done right?
