Turn over acts like wants to crank but will not start. I have replaced spark plugs, new injectors and new fuel pump two weeks ago.

We need to start with finding out if we have spark and fuel. Let's assume compression is ok for now but we may need to come back to this unless something just happened to this like a head gasket replacement or something else like this.
Here is a guide that will get us started:

However, let's start with checking fuel pressure just to make sure it is operating and getting to the rail.

Once we know that is ok, let's pull a plug and hold it against the block and crank the engine to see if you have spark.
Do you have a theft light remaining on?
Let's start with this info and go from there. Thanks
