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.

What makes it vapor lock


If it is a gas engine, its almost impossible to get vapor lock.
Vapor lock is when liquid gasoline turns to a vapor which will not flow thru a carburetor. The usual cause was hot fuel lines going to the carb.
Since the early 1980s engines have used fuel injection which uses liquid fuel under pressure.

Where do find the vapor lock on my 1999 Buick century


Vapor lock occurs when the gas in a fuel line turns from liquid to vapor, before it reaches the engine. The first signs of vapor lock are normally when your engine begins to run roughly. The engine may sputter and hesitate. It will then stall completely and refuse to restart. It may seem like the car is out of gas or the fuel pump has failed. While these are possibilities, vapor lock may be the problem.

I put gas in my 1998 Camry, drove about one block and it stopped. It tries to start when but will not turn over. It's not the battery, energy still on in vehicle, not the starter, no clicking, not the...


IF it was vapor locked it would still turn over just not start. If it was vapor locked you can just loosen the gas cap and it would immediately start. If it is vapor locked you will hear a hissing suction sound while loosing gas cap. Its trying to get air.Quick fix leave gas cap off..Drill a small hole in the center of gas cap. It will let it breath. To fix it right.Buy the filtering charcoal canister. Never put that extra 25 cents in at gas station once gas nozzle clicks. That extra gas goes down the vapor filtering line causing it to clogg up over years.

Can vapor lock in the cooling system cause the engine to not spark and through off the camshaft sensor on a scanner in a 2001 dodge dakota sport 4.7 L v8 magnum manual transmission


No.
To begin with, there is no such thing as vapor lock in the cooling system. Vapor lock is when liquid gasoline vaporizes due to excessive heat. If the engine got hot enough to turn coolant into vapor the engine would seize up.
Do you have trouble code numbers ?

So tell me does a vapour lock ,comes from a hole in the muffler,and would that make a cranking sound come from your engine


To promote easy starting, all gasolines contain volatile constituents that under some conditions, such as high ambient temperature, tend to produce more vapor than the fuel-system vents can handle. The action of an engine-mounted fuel pump, in decreasing the pressure at its inlet, tends to vaporize the fuel. If the vapor forms faster than the pump can draw it from the fuel line, the flow of fuel to a carburetor is effectively stopped and the engine stalls. Vapor lock is much less likely on a fuel-injected engine with an electric pump in the fuel tank. However, an engine with port fuel injection may experience vapor lock if the injector or fuel overheats, or if the Reid vapor pressure of the fuel is too high.

What is vapor lock?


Vapor lock is when a fluid in a closed system, such as in a hydrolic system, gets get hot enough to boil and produce vapor which unlike a fluid can be cimpressed thus rendering hydrolic systems inoperative. Fluids act as a solid when pressure is exerted on to them but in their gaseous state (vapor) they can be compressed and the pressure needed to move pistons is instead absorbed by the gas rather than applied to the pistons.
