Hi,
If you have spark, you should have at least a change when using starting fluid. As far as the CKP, RPM signal, if you don't have that, you shouldn't have spark. LOL Sorry, that even confused me.
Could you record it cranking and upload it for me to hear? Also, reconfirm there is spark to the plugs. If there is, try the starting fluid again. It should at least try to start.
Let me know.
