My 85 efi 4runner always starts but after it's all warmed up and I shut it down for a minute or two sometimes it will just turn over and not start, then after 5 minutes or so she will start right up, what is my problem? engine has alot of miles but the air filter is new so are the plugs....maybe the fuel pump or fuel filter, I had this happen 3 times in the last month it only happens when I shut it down and try to start it within a couple minutes - the truck has never let me down but I'm a little worried about going wheelin and not getting the truck started....I was thinking of cap and wires but I really don't have a clue to this issue.
