The other day, after driving for an hour, then sitting for a couple of hours, I went out to start and heard a running water sound. I shut it off and turned the key on and the fuel priming sounded a little funny. Could it be the fuel pump going sour? Is it what I think it might be?
When the A/C evaporator drain became clogged in my 1999 C5 coupe, water built up in the evaporator case (before it overflowed and ruined the computer below it). Before it overflowed, I could hear a "water" sound when I sat in the car - I believe it was the water in the case "sloshing".
