Hey guys, My sister has a automatic 2000 Hyundai Sonata GLS, and for the past 2-3 months every time she fills it up with gas, it will turn over for about 10-15 seconds before starting, and then when it starts it will sputter out and die unless the throttle is being pressed. But other than that it starts and runs fine every other day. any ideas? thanks for the input!

DESCRIPTION:
A 1999-2000 Sonata, may experience a crank no start, hard starting after filling with fuel, or erratic idle speeds. One possible cause for this condition may be a mechanically stuck open canister purge valve (P/N 39460-38650).

SERVICE PROCEDURE:
If one of the above conditions exists, inspect the canister purge valve and intake system for vacuum leaks.

Remove the canister purge valve (see photo below) and blow through the valve. No air should pass through the valve when it is removed from the vehicle.

The canister purge valve is located near the right side and below the intake surge tank.

 

just a swap in? also where would i find the part? just a napa or would it have to be a Hyundai dealership

 

would it be this NAPA AUTO PARTS) or this KIA, HYUNDAI VALVE, PURGE CONTROL SOLENOID P/N 3946038650

 

I would get one from a dealer or an online source of Hyundai parts like:
Hyundai Shop | Hyundai Aftermarket | Hyundai Accessories | Hyundai Parts | Hyundai Dealer Accessories
or
Hyundai Parts Online Parts & Accessories Catalog

 

ok thanks, so is it a quick swap in swap out?

 

The first link brings up an error. The second looks correct.

 

I'm having a little trouble finding the part. some say $20, while others are telling me its for a santafe, and some are telling me its $60.

 

That's why I'd just go to a dealer and have them look up the correct part for your car/engine combination.

 

ok thank you!
