AND my fuel pressure regulator so i know which one exactly is bad cos i dont have a lot of cash, almost none. car ran fine when i putit in garage last night. got up to go to work, turns over, but doesnt start. checked fuses under hood and dash. o.k. i then checked fuel pressure by depressing that stem on the fuel line. nothing. i then removed the tube to the air filter and sprayed some starting fluid into the tube towards carburator, started up and stayed running while i continued to spray. so i assumed fuel pump. only to find out about this pressure regulator crap, which i know nothing about. help!!!!!!!!!
