I have the popoff valve update, but there was a kind of "poof" right when it quit.

When I turn the key to the on position, I hear a relay click once in the fuse box - I assume that is the fuel pump relay.

The fuel filter was replaced july '06 and the car has less than 1000 miles since then.

I'm thinking the problem is something I initiated since it went "poof" when I gave it gas. I think I'd heard it backfire once before when the engine was cold and this did not sound quite as pronounced. I gave the engine a quick lookaround and did not see anything disconnected - it is a squeeky clean engine so connections in plain sight are pretty evident.

This happened to the guys conducting the state inspection on the car, but they let it sit in their shop for a few hours and it started without any corrective action.
