The coil packs and injectors are fed through the same fuse when the key is on.
Check the fuse.
Look in your owner manual at the fuse assignment to see which one it is.
You may have caused a problem from the work you have done.
If it's not blown, recheck the crank sensor plug up and all other harness you has pulled apart.
Don't change parts just on a whim unless there is a proven need.
You only raise the possibility of making extra issues for yourself.

When my 2002 had an intemittent crank but no start, I checked the codes. It did not have a check engine light. It had a P1000 which could be caused by deleting codes, or disconnecting the battery. Since I had not disconnected the batttery or deleted code, I replaced the PCM relay and that fixed it.
