Condensation in my gas tank

My 06 V6 Sonata sputtered upon fire-up this morning. I turned off the
ignition, turned off the defrost / blower and the radio. Tried it
again, and it did it again...until I tapped the accelerator, which got
the engine humming in no time.

There was very little gas in the tank at the time. I live in
Washington State...and it's been real wet here and cold. I'm thinking
water in the tank ?

 

People used to add drygas to absorb moisture. Now that gasoline is 10
percent ethanol (drygas was usually isopropal alcohol) it is no longer
needed. Just fill your tank and don't worry about it.

Old New England trick for this was to always fill the tank
completely when adding gasoline. I guess that filling up more
often might help too.

How well this works these days, I can't say.

Water in the gas is a possibility, but there are many others as well.
If the problem is reproducible, the dealer should be able to narrow
the potential causes. With the dealer's scan tool, the technician can
monitor which cylinders are misfiring. If all or most are misfiring,
the implication is that there's a fuel issue. Whereas if it's one or
two, then we could be looking at ignition, wiring, or mechanical
issues, but since the offending cylinder is identified, there's less
to check.
