QUESTION: yes ive turn it with a end wrench with spark plugs out

Answer
Does the engine turn over easily by hand with the spark plugs out ?.

 Are you POSITIVE that the new battery is fully charged ?. Most batteries do not come fully charged. Try using jumper cables from another vehicle.

Are you sure that the battery cables are no corroded internally and or have corroded end terminals at the battery ?.


Without personally having access to the vehicle, I can only give you suggestions on things that I have run across over the years.
