No spark and i can only get 5V at the coil.

Just for testing. Actually I would not, I would test "as is"

One easy way is to attach a clip lead direct to the coil + and run over to battery (starter relay big stud) This will "hot wire" the thing for a test. See if you have spark then

He is testing it as is and it won't start. :D
Jump it and see what it does.
