You may need to check compression. Use a gage and check for proper fuel pressure. If your spark---timing and compression are ok, I don't know why it wouldn't hit with starter fluid? Can you check if the system is running rich or lean? Any applicable trouble codes? Are the spark plugs dry?

Remove air filter and pour fuel in the throttle body. Does it start?
