Where's my electrical gremlins? Wont start!

no clue as to what we are working on here, but , the starter relay needs to see a ground/Neutral Safety Switch. double check ALL your grounds. you really need to get you a service manual and test your system
I have a service manual... is it the wiring diagram I'm looking for? I changed the nuetral switch twice and then bought a new wire harness for it. Are you sugesting the ground to it may be bad?
