5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
Ok runs fine but when its upto operating temp. and you shut it off it won't start again untill you pull the relay that is under the driver seat. As soon as it starts you plug the relay back in and off we go. Do you have any ideas?? when the relay is unpluged the car barely runs so you have to be fast. I don't know what the relay is but the guy that sold the car to me told me to do this when it won't start. Thanks anything would help.
Any idea why it starts when the relay is unpluged and not with is pluged in. I'm going to replace it to see if that helps. I noticed it gets pretty hot.
