Get second opinion vapor lock is kind of rare for vehicles because of the evap and fuel pumps ---more than likely problem with your fuel pump module which has vapor {evap} lines as well as vent lines attached to it inside tank i would also check the fuel pump relay it is in the trunk drivers side the relay over heats than pops open shutting off fuel pump --that and check your evap canister may be clogged -dirt or fuel ---

You need a different mechanic. Vapor locks stopped in the 60's.

SOURCE: 2005 Chevy Impala...all I did

the lower radiator hose is a return hose and there are no vapor lock issues. If your coolant level is full when you start your vehicle and when it heats up and the system pressurizes your coolant expands with heat and then that excess pressure will go through the overflow outlet to the reservoir and the reservoir has a relief opening near the top to relieve pressure or for excess fluid to come out. If the lower hose is just warm then your water pump may not be circulating properly (be sure to check belt for tension no more than 1/2 inch of play should be present). One messy way to test water pump would be to first drain coolant if it is good to reuse it, then remove the lower hose, open the radiator cap and put a water hose in it and turn on half way. Look at the volume of water coming out and have someone start the vehicle and idle at about 2000 rpm if that volume has not doubled your pump is bad

I need to know where to find the fuel rail on my 2005 Hyundai


doubtful that vapor lock is an issue on a fuel injected car. it was something that happened on old vehicles, and you just don't hear about it any more. It doesn't happen because of the high fuel pressure in the fuel lines of fuel injected vehicles. If the vehicle is cranking and won't start, it might be a fuel issue--getting no fuel because of a fuel pump issue. But not vapor lock.

Vapor lock is from boiling fuel check fuel line for factory securing clips on frame. check for exhaust leaks added heat is causing your problem. Also test fuel pressure if low this also helps the fuel to expand easier.

How to fix code po455 on 2005 cobalt


I researched this and found the following information. Hope it helps: P0455 means a gross leak detected in the Evaporative Emissions System. Some call this a "gas cap" code, because the most common cause a loose or failed gas cap. But it could be caused by any vapor leak in the fuel tank, filler neck, or anywhere else in the vapor management system. If it isn't a gas cap, you will need tol take it someplace where they have a smoke machine that can find the leak using smoke.

We also own a 2005 chevrolet impala with strong gas fumes, inside of the car driving or just idling..also fumes are strong when the car is just idlin. Took it to the mechanic and put the car on the rack,...


I would have someone check under the front of car while engine was running. Maybe then a gas leak could be spotted. Did he check the charcoal canister-it's a gas vapor collector from the gas tank, and maybe located at front of car. If the canister is full and not working to purge the canister and send the collected fuel and vapors into the engine, it might be what you are smelling.

Diagnostic code p0455


Hi Rad,
P0455 is a large emision system leak. A common problem with this is that the evaporative emision vent valve located up and behind the driver side rear wheel is malfunctioning or leaking fuel vapor. Have it checked and see if it solves the problem.

I hope that helps.

Regards,
Jeep Brainy

I have 2000 chevy impala 3.4 engine i have check engine light with this code p0442 took it it to auto zone they said it was a small leak dont know where to start


This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
With a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses
