Removed and replaced one 1993 previa fuel injector now engine sounds "seized".Doesnt even turn Could it be vapor lock?


no
more likely a hydraulic lock from excessive fuel on a piston cause by leaking injector /seal
remove the plugs and see if the engine will then turn over after it sprays the fuel out of the problem cylinder
vapor locks occur in fuel lines where the fuel boils off filling the line with air and locks the fuel by not allowing flow in the line

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.

Why does fuel vaporlocks after warm?


Gasoline has what is called low vapor pressure, in English that means it evaporates very quickly, most people know this. The vapor lock is when there is only vaporized gas in the fuel line, it has to purge out just like air before liquid fuel reaches the engine and that is called "vapor Lock". You can wrapping the fuel line to insulate it from engine heat, that may help.

How do you fix vapor lock?


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.

Vapor lock? On a 4.3. 2000. Chevy. Blazer


Not really possible.
Vapor lock was when liquid fuel would vaporize in the steel line or carburetor from excessive heat.
Since your Blazer is fuel injected, the fuel can not vaporize in the line.

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.

Leak on fuel line e 150 1991


Change the Fuel Filter the process is
  • 1

    Park the van on a flat, level surface. Ensure the parking brake is set.

  • 2

    Open the hood to locate the fuse panel. The fuse panel is located by the battery. Find the relay for the fuel pump and pull it out by hand.


  • 3

    Start the van and allow it to idle until it stalls out. This will depressurize the fuel system.

  • 4

    Locate the fuel filter under the van. The filter is located by the driver door mounted along the frame rail.

  • 5

    Disconnect the inlet fuel line with the quick-disconnect tool. This tool can be purchased at any automotive-parts stores. Place the tool over the connection and pull it toward the filter. This will release the fuel line from the filter. Repeat to release the line on the outlet end. Place a piece of masking tape over the inlet line to help remember which line is which. The inlet line is the line coming from the fuel tank into the filter. The outlet line is the line that runs to the engine from the filter.

  • 6

    Unbolt the filter from the bracket assembly. Slide the filter from the bracket.

  • 7

    Slide the new filter to the mounting bracket. Tighten the bracket with a socket wrench. Ensure the arrow is pointing toward the front of the van. The arrow designates the direction of the fuel flow.

  • 8

    Push the inlet line onto the filter. The line will lock in place. Ensure the tape is removed before installing. Connect the outlet line to the filter. It will lock in place also.

  • 9

    Insert the fuel pump relay back into the fuse panel. This will pressurize the fuel system.

  • 10

    Turn the ignition to the "start" position and allow the fuel pump to prime itself and push fuel through the lines. Attempt to start the van; it may not start right away. Once the van has started allow it to run for five minutes and observe for leaks.

    Need to change fuel filter on 97 chevy lumina


    Follow the steps care fully

    Open the hood and relieve the fuel system pressure. On the fuel rail, right before the first fuel injector, locate the Schrader valve-similar to a tire air valve-on the inlet fuel line. Using a small screwdriver, depress the stem inside the valve while covering the valve with a shop rag to catch the squirt of fuel.

    Raise the back of the vehicle using a floor jack and support it safely on jack stands.

    Locate the fuel filter along the frame rail-passenger side-of the vehicle, near the fuel tank.

    Unplug the quick-connect fuel inlet line on the back of the filter by pressing the lock tabs. Push the connector towards the filter and then pull to disconnect the fuel supply line.

    Disconnect the outlet fuel line from the filter-the line going toward the engine-by using a backup wrench to hold the line nut while disconnecting the lock nut on the filter with a tube wrench.

    Remove the filter from its mounting bracket and install the new filter in place, making sure the arrow on the side of the filter case points toward the engine.

    Install the outlet fuel line. Tight the lock nut finger tight, then hold the fuel line nut with the backup wrench and tight the lock nut with the tube wrench. Make sure not to over tighten the nut to prevent fuel leaks.

    Press the fuel supply line fitting against the small tube at the back of the filter until the lock tabs snap in place.

    Lower the vehicle, start the engine and check for leaks.

    I have a 87 mustang and it has a mr gasket electric fuel pump. It vapor locks all the time. i have to take fuel line off turn switch on let fuel pick back up then plug the fuel line back up and it will...


    Actually vapor lock refers to a condition in the intake manifold on a carbureted engine. You don't have vapor lock. What you may have is a filter inside the tank, its nicknamed a sock. Its a fine mesh screen and may be plugging up. When you pull the fuel line the fuel flows back and unblocks a small section , until it starts too **** again and re plugs. You may also have fuel pump that starts to lose power when its gets hot. Lee
