Need a code scanner hooked up to it to find out why the light is on.
If there is an advanced auto or auto zone near you, go there, they can hook one up to get the code, that will show what is wrong.

Where is the fuel regulator located? And how can I tell if it's bad


Some fuel regulators are located in the tank as part of the fuel pump assembly. If the fuel pressure regulator has gone bad, it can leak fuel in the engine, contaminating the engine oil.

Symptoms of a bad regulator is:
Poor gas mileage.
Smell of gas in the engine compartment.
Fuel is leaking.
Black smoke coming out of the exhaust (tail pipe).
Failed emissions test.
Check engine light is on.

Check engine light is on and the car runs rough at idle only. There is also a burning smell when I exit the car coming from under the hood. What could be the issues?


have a parts store pull code, to see what sensors r at fault, tps throttle position sensor may need adjust, oxygen sensor needs replaced, may have two ? both need replaced. gas cap might b faulty ? in any event, the trouble code must b cleared out from computer, after repaired is made. if engine light comes back on, reclear it. sometimes intermittant sensor problems occur, engine light comes back on. well, the gas we buy with ethanol is killing our engines, put some fuel stabilizer in @ next fuel up. but try some fuel injector cleaner first, winter gums up injectors, soooo ! fuel filter replacement is always in need, people don\'t get it, replace all filters, air, fuel, oil, get it ? maintenance is a necessary evil. u change yur clothes ever day, right ? well, same thing., good luck, ken

Engine management light stays on


check whether you do have a smell of fuel or burnt gasket in the radiator after remove the cap. If so then you have an overheated engine and blown gasket. Or check whether if you have either water in engine oil or vice versa. Having any of the two,surely you have to remove cylinder head for renewing cylinder head gasket etc.

O2 sensor engine light stays on, smell gas in kia as it warms up on cold days


o2 sensor is probably bad and so the car is unable to make proper adjustments to the air/fuel ratio. What you likely smell is your car running rich, meaning there is too much gas for the amount of air the engine is taking it resulting in gas that is getting burned completely and is going out through the exhaust. Is probably going to decrease your gas mileage. You should probably get the o2 sensor checked out.

The check engine light stays on my gas smells bad and my oil smells like fuel


You need to have the trouble code pulled so vehicle can be diagnosed. I suspect the engine is dumping fuel into the oil. If your fuel pressure regulator diaphragm ruptured this would give you the gas in the oil and a rich DTC. You could also have a coolant temp sensor that failed, making the computer think it's -40 degrees and commanding too much fuel-this too would make your oil smell like gas.
Trouble code would help in determining the cause. You can also remove the vacuum hose at the fuel pressure regulator-front left side of engine, on the fuel rail. It should be dry inside vacuum hose, if there is gas, the FPR diaphragm ruptured and more than likely that's the root cause of your problem.
