Hello,
If you are able to start the engine for a little bit with starting fluid, it points to fuel delivery issues.
Are you able to verify that the pump is turning on?
A faulty relay will keep the fuel pump from working.
If there is not enough fuel pressure the engine won't start.
Which could be due to a clog in the fuel line or a bad fuel pressure regulator.
This vehicle should have 58 PSI (+/- 5 PSI) of fuel pressure with the key on and engine off.
Here is a guide on how to test the fuel pressure:

Please let me know if you have any questions.
Thank you.
