Q&A: Fuel percolation chokes engine
Indubitably: No dealership has been able to fix the problem with my 1996 Toyota Tacoma. For a year now, once the agency has been driven for at least a half-hour in warm endure and it is turned off and sits for a few minutes, it will not restart unless you cool one's heels for at least 40 minutes for the engine to cool. It seems like it wants to start but the conduit is "thirsty" for fuel.
Once restarted after the 40-asset minutes of waiting, it runs just exquisite. This problem doesn't happen in the winter, only on hot summer days, and every once in a while it idles crudely, but not often. It has been extremely frustrating to have to always wait awhile after driving it somewhere before I can tour it again.
ANSWER: You've accurately described "vapor coop up," more formally called "fuel percolation." This occurs when machine heat trapped under the hood boils the game fuel supply in the fuel rails on top of the apparatus. The bubbles in the boiling fuel prevent respectable fuel pressure necessary to deliver stimulate from the injectors. Until the fuel cools, stops boiling and the air bleeds out of the system, the locomotive won't start.
