how to KEEP teener running in hot weather, cool and cold weather good for 74 teener - WHY Options

[9fourteen14]

I have stated my question in a way to get the most responses/help/ideas possible.

when the weather is warm to hot and I have driven it for 4 miles or so, It really
wants to die. and then if i drive it any longer it will die in the hot weather.

THEN

after just waiting until (it seems like cools off - because engine if not running
it will start right back up and go.) in the hot weather.

I know others have experienced something like this BUT
I have never seen any answers that come close to my situation.

thanks for your help.

Vapor lock, as I understand it, is when the fuel lines/pump get hot enough from engine and/or environmental heat that the liquid fuel starts losing its liquid properties resulting in the fuel pump unable to push it through the system. Or sumpin' like that. The "fix" in many cases was relocating the fuel pump from the engine bay so it wouldn't get all that engine heat.

You really need to tell us if it's carbs or FI you're dealing with here.

Edit: sorry, I see you say it's all original, so I'm going to assume FI.

umm on vapor lock... that makes sense.....
yes i have original 2.0 D-jetronic system in the original location (as is everything else)
that entire system works as documented.
ah ha now I understand why i have heard people say they have moved the fuel pump. but there must be another solution?

what else have you heard people do to solve this?

you have enlightened me on vapor lock.

thank you

NOW let me point out something else.
someone pointed out to me that is it NOT vapor lock.. because when you start car let it run stop car and look at spark plugs they have soot on them.
so this means something is burning very rich... too much gas...
so the 5th injector (btw all injectors are new) is shoot too much gas and when car gets hot/warm it is SUPPOSED to stop shooting gas. but it does not and the car shuts off.

other idea is compression. this is the route I am going to research and look into more. it is my understanding valves have never been done.
