1993 Chevy Lumina 6 cyl Front Wheel Drive Automatic
I have a 93 Chevy Lumina 3.1 L. I have been having problems with it not running when it warms up. (Like it starves for gas) If I run the engine until it's warm and shut it off it will not restart until it cools off (15-20 minutes). I have already replaced the fuel filter. Same problem. I just checked the fuel pressure, at the rail, and this is what I came up with.
I have good pressure before I start it and while it is running it is also good. I then waited for it to reach normal operating temperature and there were no changes to the pressure. I shut it off and tried to restart it and I had NO pressure at all and it wouldn't start. I checked for leaks and didn't find any. I'm sorta lost here, cause it only seems to happen when the engine is warm. If I try to start it when it is cooled off it will start right up.
Any help with this issue would be greatly appreciated! I have never worked with a fuel system before (other than pump and filter replacement on other vehicles) so if you suggest checking any components please describe to me where they would be located to help me out.
Thanks in advance!
have the same problem?
