Hi,
Have you checked the fuel pressure? If you are not hearing the pump, that may be the issue. Also, if you have carb cleaner or starting fluid, it would work much better than WD40. I'm not sure if WD40 would work, but anything is possible.
Here is a link that explains how to test fuel pressure:

You will need a pressure gauge, but most parts stores will lend one to you. Also, I attached the manufacturer's pressure specifications below for you.
Try this and let me know the results.
Take care,
joe
