2002 Sonata LS 2.7L
When trying to start the car, it rolls over for 10 + seconds before it
starts. Once it does start it idells rough until the excess gas is burnt off. The car runs great going down the road. I've replaced the plugs and the coill. I didn't replace the wires, but they have only been on the car for 14 months. Any help would be great! Thanks, Dave |

Any difficulty restarting after fueling?

hey, try cleaning out the throttle body, this causes a few problems on the
newer sonata. also try replacing the fuel pump relay, its 5 years old now and may be getting lazy |
Re: 2002 Sonata LS 2.7L
It doesn't seem to matter either way. It acts like it's flooded or not
getting enough spark, but it doesn't miss after it's running. Could it be that the injectors are staying open after the car is shut off?

Re: 2002 Sonata LS 2.7L
I cannot figure out from your reply whether you have a long crank time
after refueling. What I want to know is, when you pull into a gas station and fuel the vehicle, do you then have the long crank time when restarting it, or does it start normally? |
Re: 2002 Sonata LS 2.7L
I'll check tonight when I re-fuel.

Re: 2002 Sonata LS 2.7L
Damn you're good. It started right up. What is it?

Re: 2002 Sonata LS 2.7L
It started right away once. After that the crank time was long.

Removing the cap would let air in and temporarily vent the tank. Hopefully, hyundaitech will chime in, but that would be my first guess given the circumstances you describe. Matt |
Re: 2002 Sonata LS 2.7L
I was hoping for a long crank time immediately after refueling. That would
indicate a stuck open purge valve. Since that didn't occur, I'd suspect a faulty fuel pressure regulator bleeding the fuel pressure off intermittently when the engine is off. The only way to know for certain if that's the problem is to have a fuel pressure gauge attached and verify that the pressure drops below about 20PSI after turning off the engine immediately prior to the condition reoccurring. |
Re: 2002 Sonata LS 2.7L
The short crank time after my first post was a fluke. I've filled the tank 3
times since then and let the car sit for a few minutes. Each time it was a long crank time. The car will start with a short crank time if it only sits a few minutes after it has been shut off.
