Re: collapsed fuel tank
The car was running rough on the first start after a fill up with gas. No problems any other time. After about four fill ups each with the same problem I took it to a dealer. The code indicated a problem with the purge solenoid. The dealer replaced that. We picked the car up and then heard what we think was fuel sloshing behind us when we stopped. We had not heard this before. About 3 days later on the way back to the dealerthe gas guage suddenly dropped to empty. I stopped and filled the tank. It took six gallons. The dealer exposed the tank and it is collapsed. The dealer thinks the defective purge valve may have played a role in it. From other things I have read it seems that there may be a valve in the tank that fails and the fuel pump and manifold pressure create enough of a vaccuum that the tank collapses.
