awood94

ok so I have 1994 z28 lt1 I received from my buddy for extremely cheap hasn't ran in 2 years I just wanted to see if it would start or run the injectors where not spraying fuel so I took off the fuel lines and it was priming just fine replaced the fuel regulator and still wouldn't spray so I punched out the diaphgram in the old one hooked it bad up the injectors spray just fine engine starts for a couple second then dies again obviously I cant leave it that way so I checked the vacuum line that goes to the regulator and theres no suction whats gonna be the next thing I check?
