Your question is too broad as far as the diagram. What is the problem? Will it crank? Will it start and run? How long since a tune-up? If it cranks good but won't start, have a helper crank it, while you check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure.
Did you check for applicable trouble codes, before you unplugged anything? If not, why not?
Is your ac compressor clutch engaging?
