Re: Black stuff on & around fuel cap. What is it?
I guess it pretty much has to be exhaust. How is your exhaust system? Could it be leaking and rising up into the cap area? Is the pipe secure in the gas compartment? Does it look like rubber or plastic, or soot/ exhaust?

Hello, Check your fuelcap and tighten it. The code may clear or go to an Autozone, Advance or Oreillys for a free scan and reset of the computer.
If the problem is not with the fuelcap, you will need to go to a place with a "smoke machine". This machine will detect leaks in the fuel vapor system. It can be a vent line, or any connection from the fueltank to the front of the car.
It is an Emissions problem and does not indicate a fuel leak.
The purge valve is supposed to keep sucking vapor from the gas tank, through the charcoal canister, and it never works right. A loose gas cap can not only cause it to flash a problem, but will also cause too lean of a mixture and harm the engine. The purge valve system is prone to way too many leaks, and the consequence of not letting enough vent air into the gas tank, can be a collapsed tank or a blown fuel pump. It is not worth the risk. The easiest thing to do is vent the tank to the open air after the charcoal canister, as all boats, lawn mowers, etc., are, and all cars used to be. But then also plug the line going to the air intake, because otherwise it will be a leak and cause too lean of a mixture. The purge valve is another bad idea that eventually is bound to have catastrophic results. Too many car engineers forget cars spend a decades in freezing cold, blistering heat, torrential rain, vibrations, etc.
Have you replaced the battery recently....check connections, make sure you have good ground
Batteries are good for about 5 years....this heat will kill an older battery...if it is not the battery then I lean towards the starter needing to be replaced.
You may have a vaccum problem as well.
Check fuel cap light will not immediatly go out upon replacement of the fuel cap. Might take several days. You could go to a local autoparts store and have them read the trouble code (for check engine light) and reset it. If it was indeed the fuel cap the light should stay off after resetting it. Most autoparts stores do not charge a fee to do this.
