IAC, throttle body, fuel injectors, ECM, ICM fuel pressure regulator are the likely culprits here. Put a scan tool on it. OBD I not OBD II.

- We Checked the throttle body it's fine. When put starting fluid it runs in the throttle body. I looked at the fuel pressure regulator its seen to keep the car on longer when I take off the vacuum line the car seems to stay running a little be longer but.I Don't really know to test these out to see if that the problem
- The ICM was replaced and i don't know if thats a bad one I bought but when the old was in still the same problem.
- ECM I think its working I'm not getting any codes from the obd 1 only then I'm getting 12 12 12 thats it.
- I'm not getting fuel injector pulse at all on the rail
- and checked all fuses
- please if there any thing else i should test out let me know thanks.
