This has been a nightmare week with my car. I recently had the fuel pump replaced when the car would not start. It's been fine for awhile and once again it is quitting on me and the garage cannot determine the problem. I went back to them thinking maybe the fuel pump was defective, because it seemed like it wasn't getting gas. They put another one in and same thing. It will go for awhile, then quit and if you let it sit for an hour or so, it will start up. The garage could not get it to quit, just seemed to happen to me, so they basically said they couldn't help me because until it doesn't start they can't determine the problem. After every tow into them it has started up. From reading the posts it seems it could be a number of things. If I'm correct the problem now is, it's not getting spark...it is getting gas. What I want to know is, I was given an ignition module from a friend to try and I don't know how to put it in or where it goes. I figure I might as well try it and see what happens. It has the part number on it and I'm sure I can find on the internet if it is the correct one, it should be since it was for his 91 Lumina. Just need someone to tell me where it goes....believe me I'm no mechanic but if I have the info I can do it....thanks......Nancy
