Vapor lock is more or less impossible with a fuel injected engine.
Years ago when engines used a carburetor, liquid gas flowed thru the line from the tank and sat in the bowl of the carb until it was pulled thru the venturi into the intake. If the fuel line or carb became too hot, the liquid gas would vaporize.
Fuel injectors accomplish the same effect by spraying a vapor of fuel into the cylinders under pressure.

Having trouble with vapor locking

Vapor lock can be caused by many different things, all coming down to the same root cause: too much heat in the fuel feed lines.

Low fuel pressure can cause the amount of heat needed to vapor lock to be lower than normal, so checking fuel pressure is important. Fuel pump going out feels a lot like vapor lock.

Engine overheat can also cause vapor lock. Clogged fuel filter can cause vapor lock. The fuel line should be routed away from the exhaust system.

Vapor lock when the engine is runnig. How do I fix this issue

"Vapor lock" is a condition that occurs when fuel becomes heated to the point of evaporation. If your vehicle is truly vapor locking, it means that something hot is coming in contact with your fuel line somewhere, overheating the gasoline to the point of it vaporizing. This is HIGHLY UNLIKELY. If you truly do have a vapor lock condition, find out where the fuel is becoming heated and fix that condition.

Vapor lock, from my experience, is a pretty rare problem. Unless you have put too much starting fluid in through the air intake. If you have not tried to use starting fluid, you should try to spray some through the airfilter, or the air intake for the motor, while someone is trying to crank it. Do not over-saturate it, or it will cause vapor lock. (vapor lock is all fuel vapors and no air). I have a suspicion that a few squirts of this will get it to fire up. If it starts but then goes out after the starting fluid is burned up, then you may have a problem with the fuel not getting to the engine.
