from what I have learned from this forum, my buick regal has a leak in the braking system which causes my car to stop running after applying brakes. have already spent over $2,000 on other items and still just quits running and then wont start until it is jumped off.
First off you have to problems not starting until jumped is not related to vacuum leak you should be able to find the vacuum leak with the hood up and engine running it will sound like an air leak trace it out and find it.
get professional help, or sell the car. anything gm is of poor quality
youve gotten bad advice somewhere, i suggest starting over and giving complete details and model etc,because a vac leak will not cause a no start until boosted unless you also have a bad battery/charging system.
Light a match let it burn then blow it out while the doors and windows are closed so none of the smoke gets out. If tht don't work lots a fabreeze
