I have a 1997 metro lsi 4cyl. it starts and runs fine until you shut it off.If you start it right backup it does fine,but,if you wait 5 to 10 minutes it won't start until it completely cools down.Have tried another computer and it didn't help.Took it to a mechanic and he ran codes for me and it brought up nothing.Do you have any ideas?Thanks alot.
