Kia sedona 2002 smell gas in the interior of car

You may have clogged the injectors.

Most vehicles have the fuses listed in the owners manual in the glove box or buy you a service manual from a parts supplier like Advance, Oreily's etc. .

Could be a sensor , but without testing , this would be a guess ! Have seen TPS - throttle position sensors on chysler products do this , Mass air flow sensors on GM vehicles , plus bad IAC - idle air control motor . Don't think you would like to replace all these parts , your best bet , take it to a qualified repair shop . Have it tested !

Bad fuel pump, stopped up fuel filter, mabey? First check for vacume leaks.... may try unplugging the throttle position sensor. Plug it right back in... just check the connection.

I think it might be friction on the tires making the smell. About getting the car out, if you can still open the drivers seat door, and do this...
Get it towed!
If that doesn't work...
Depending on how big the ditch is...
Big, Ramp Small, Rent a crane!
(I was being sarcastic right there, but it might work! Ask a van expert first though...)

May be the starter or fuel pump. Might not be getting gas after turning it off. the gas may be settling to fast into the fuel pump and none staying in the engine. My friends SUV does not start unless you pump the gas pedal. Not an expert but its what i know it could possibly be.

The heater core is leaking into the heaterbox under the dash. Which is why you smell antifreeze/coolant inside. After a while (if left go too long) you'll notice antifreeze on the floor/carpet and possibly running out from under the vehicle as it flows out of the drain for the air conditioner (the heaterbox has a drain in it to let out the moisture produced by the a/c)

sounds flooded, hold gas pedal to floor and try to start,if starts keep pedal down until motor clears out and runs good, if no start, check spark plugs. maybe fuel fouled and need replaced. make sure you have spark before installing new plugs.

check for bad gas , check timing belt

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.
