Yea, longer cranking times, but then .5 sec is not much of a difference. This occurs because a lack of residual fuel pressure. And that can be caused by leaky injectors, a bad fuel pressure regulator, or a weak fuel pump. But there can be other causes as well (see paragraph below). Check you spark plugs 1st thing in the morning for fuel fouling if you suspect the injectors.
The carbon canister is either in the engine bay (behind the air box), or in the trunk (under the spare tire), depending on the model year. The fuel system is designed to have some spare room for fuel vapors to expand. If you top off at the pump, you're leaving no room, and when the gas expands, it forces fuel to exit through the canister. If you repeatedly get enough fuel dumped into the canister, it gets clogged up, and that can cause a number of problems- failures with the fuel pressure regulator, fuel pump, or injectors. All the components in the fuel delivery system work together, and when one part goes bad the others will follow along shortly after.
But enough of that mumbo jumbo . . the more probable answer to your problem is hopefully simple: usually the clamp on the fuel line coming out of the fuel pump is loose and leaking a little . . this is where the lines are most likely to leak, if they will. Or the seal around the pump is leaking or venting vapors. To find the pump, have a look at my
writeup.
