Hey Guys,
I gave my mechanic to put engine in my 2002 HYUNDIA elantra automatic. he put the engine in but he said car is not starting because couple parts or sensor are missing. in the picture below the orange plug where does that go? also there is another part in other picture that missing. we dont need repair manual therefore we dont know what is the name of the part. please help. thanks!

 

is that where your fuel rail goes? IDK it looks like your fuel rail and fuel injectors are missing but I can't be too sure.
