Sounds like a purge issue. You shouldnt be smelling gas at any time unless the canister purge valve is opened. Could be an evap leak somewhere. I would get the codes read.

Replace the gas cap and check filler neck for corrosion.

When my filler neck rusted and I was smelling gas it set a SES light for an evap leak, not the low gas light. That is... odd.

No idiot light should be on when the key is pulled. That sounds like an electrical gremlin, maybe ignition switch related since most of those oddball issues usually trace back to it.

Agreed. The instrument panel cluster (IPC) has both constant 12V and a switched ignition power source available to it, but the low fuel indicator is turned on by a data message. So it could be either the ignition switch or the IPC. Swap with a local buddy to find out for sure. If you don't have a local buddy, one will be provided to you at no charge at the next local meet. If you don't have a local meet, START ONE. :biggrin:

That's what we do here :biggrin:

Too bad you're not closer otherwise I'd help track down the problem, swap switches with you, etc.
