I'm by no means an expert on this, just repeating an explanation passed on to me.
At each start up, the leak detection pump (LDP) pumps a slight bit of air into the vapor recovery system to check for leaks. If it notices a immediate drop, it will continue to pump air to determine large vs small leak. If the pump is bathed in mud and water, it may hinder its operation. On my '01, the LDP is under the hood on the drivers fender. Other years, it is located in the rear passenger fender, behind the plastic liner. I forget the price on the new pump, but it was well worth pulling off the old one and cleaning the gunk out of it. Trace all the lines out and check for dry-rot while your in there.
