Car will not start unless I spray starter fluid in carburetor what could the problem be???

Ok, now we're getting somewhere! .. Google > how to get obd 1 codes on GM.. You should see a YouTube video and pictures on the results page.. Follow the instructions and get the code numbers.. It's easy to do.. Then post the exact numbers here for more help.. I'm kinda hoping it has either a code 14 or code 15.. Let me know.. Got to have the number(s) first!

Where's the ecm located??
