Why is my Jeep vapor locking?
Vapor lock occurs when liquid fuel turns to vapor before it gets to the carburetor or fuel rail. This is a problem because pumps designed for liquid do not pump vapor very well. Vapor lock causes: Loss of fuel pressure (and flow)
What are the symptoms of a vapor lock engine?
There are several symptoms that may point to vapor lock. When your engine is warm, it may: run rough; experience rough idle; lack power; hesitate on acceleration; surge; stall and start after cooling for an hour or two; be hard to start; not start; perform poorly; Several factors can contribute to vapor lock: High underhood temperatures
Why does my Jeep stall when I start the engine?
If it starts, the fuel pump is the problem. If not, the engine should be checked for spark. It could be a sensor or computer-related problem. To be absolutely sure, raise and support the back of the Jeep on jack stands, unless the height allows you to crawl under the back without raising it.

What happens when engine heats up to operating temp?
As the engine heats up the ring-cylinder mate becomes looser so that the engine will run smoother and easier…but if there is too much wear the combustion gases will begin to blow by the ring-cylinder surfaces and will cause each stroke to lose power.

What causes cold stalling on a fuel injected engine?
On fuel injected engines, cold stalling can also be caused by conditions that upset the air/fuel mixture. This includes vacuum leaks or unmetered air entering the intake manifold downstream of the airflow sensor, a faulty throttle position, MAP or oxygen sensor, dirty fuel injectors,…

Can a fuel injection system cause vapor lock?
Although rare, a fuel injection system can show the same symptoms if fuel vapor finds its way through the delivery system. However, similar symptoms can appear when dealing with a faulty ignition coil, ignition control module or fuel pump. In this case, though, you’ll notice the same symptoms even in cold weather.
