2002 Chevy Impala LS where is the vapor canister and purge solenoid?
Car won't take gas

The 2002 Impala continued to impress its drivers with a strong engine, good mileage, and comfortable ride for five adults.
The base engine remained a 3.4-liter, 180-horsepower V6, while the standard for the LS stayed a 3.8-liter, 200-horsepower V6. The standard engine gets 21/32 city/highway, while the LS pays a small cost for its larger engine, with 19/29 mileage.
The safety for both trims is excellent, with the LS slightly better with standard side airbags.
Car won't take gas
I dropped a lit cigarette down the vent by the windshield. It went out, but will this potentially cause a fire if I don't retrieve it, and/or how can I?
I know there are 3 relays for fan control. I switched 1 and 3 but didn't see any results.
Need rack and pinnion or something interchangble
Is there a known repair for the security light/passlock problem that causes Impala and other GM products not to start for 10 to 30 minutes? If it's replacing the BCM at $500 that's fine, I just want to know that it will work. Thanks.
