Hello we have tried everything and my car will not turn over it cranks there is power changed harnesses and still nothing
please help me

 

Can you take us through the steps of what you have tried otherwise we are simply guessing here. When you say "tried everything" what does that mean.

For example,as part of everything, did you pull a spark plug to verify spark at the plug?
As another example, did you verify fuel is getting to the injectors? Do the injectors have voltage?

So,if you could, please list out "everything" you have tried.
