Excessive crank, 2007 Saturn Aura XR with 171K miles

Next time you fill up, leave the gas cap off. Does it crank quickly then?

Thanks! I'll try that.

it since the summer of 2009 and I've driven it approximately 140K miles.  The following problem has plagued me for approximately the last 12 month s:  Whenever I fill the gas tank, the very next time I try to start the c ar it doesn't start right up like it usually does but "cranks" quite excess ively.  After a few tries it finally starts up.  To put it concisely -

eral months.  Usually it starts right up with no hesitation whatsoever.  The only time it gives me trouble is when I top off the fuel tank, NO OT HER TIME.  Seriously, it has never, not once, given me a hard time starti ng except for when I top it off with fuel.  Anyone have any thoughts on w hat might be going on?

could be your vapor return line.

that's what I was thinking, or a saturated charcoal canister.

Does it start quicker under the same conditions if you use the "clear flooding" method of starting (that is, hold the gas pedal to the floor while cranking?)

good luck,

Are you packing the tank, or removing the hose the first time it clicks off?

Hmm, I've never tried the "clear flooding" method. I'll have to it that and see if it makes a difference. Thanks for your insight!

By packing the tank I assume you mean putting in enough gas to fill the tan k "neck." Well, no, as soon as the pump clicks off I remove the nozzle.
