I see you said it will run with a small shot of ether. As in will run like it should or it fires on ether and quits as soon as the ether is burned? If it will run with no issues after a shot ether I would say you have fueling issues.
Also if you re-use them soak em in the household cleaner CLR. I did this when I did my injectors and wow what a deference. They'll look close to new. :thumb:
