Question about 2001 Hyundai Elantra

1 Answer

'01 Elantra Start-up issue

When starting the car cold, even after sitting for only 4-5 hours, there is a very strong fuel odor and the vehicle struggles to idle, does so very roughly and will occassionally stall. When pressing the accellerator during this time, the engine will shake violently. After 30-45 seconds, the engine smooths out and runs normally. No codes from ECC. Any ideas?

    Car has 98k miles. Fuel filter replaced approx 15,000 miles ago. In-tank. No filter under hood. 1 Year on complete tune-up. MAP sensor replaced 6 months ago to clear codes for inspection. My mechanic tells me that without any remaining codes, we'll just be replacing sensors until we clear the issue. First "professional guess" is the TPS, but I'd rather not shoot blind.

    It sounds to me more a mechanical problem than a electrical however in cars they might of course be related. Assuming it is not diesel, does it **** false air in the carburetor? sometimes the axe of the valve has just a tiny bit too much space making it **** air and get strong fuel scents in your air intake and filter.

My Dodge caravan will not start when cold.


the entire system must be in good working condition for a vehicle to start in cold weather. Strong battery, clean cable connections at the battery, good starter, clean/gapped plugs, clean injectors, good plug wires, clean fuel filter, clean air filer, and good gas. If a vehicle sits with a partially filled tank for long periods, condensation can form in the tank and freeze. Use gas line antiifreeze in the winter.

My daughter has a 96' hyundai Elantra, It died as she let off to get off the highway, It cranks but won't start. there's a very strong gas odor coming from the intake, checked timing belt, and crankshafts,...


If your getting fuel which it sounds as though you are, check to see if your getting spark to the plugs. Sounds like an ignition system issue. Not sure about specifics on Hyundai but could be distributor cap, rotor, distributor, crank or cam shaft sensors.

When we start the car after it has not been started and engine is cold, we get a strong exhaust odor on the inside of the car until engine has warmed up


Is the exhaust loud? If not it may not be an exhaust smell. I work at an exhaust shop and we have seen a few vehicles with the same issue. More often than not, it ends up being a fluid leak (usually oil) that has flowed on to an exhaust manifold or front pipe and on start up the fluid burns off, causing the odor. Once the fluid has burned off there is no more smell. This is no to say the leak has stopped, but the odor is less noticeable when the vehicle is moving and the fluid burns off a little at a time as opposed to all at once like it does on start up. Hope this helps to steer you in the right direction, good luck!

My fuel cutoff switch was going off two days ago and i could not get the car started.i let it sit for two days and went to go start and i was getting a strong gas odor from inside of the car it wasnt even...


if you have tried starting it for a while , this can give off a petrol smell because if the engine isnt firing then the bores are getting floaded , the fuel cut off switch should only switch off for a reason ,, EG head on bump , part from that the switch could be faulty. but when the car runs after a short while and still stinks of fuel i would advise to get it checked out asap .. matdav69

Bad fuel odor


1 - Is your check engine ligh ON - If so have the car checked for codes

2 - Do you notice if your car is harder on fuel - elantra's are known for having an 02 sensor stop working and not turning on the check engine light.

2005 nissan sentra 1.8 liter wont start cold ...


These vehicles had issues with fuel pressure bleeding down when they sit for a period of time (like overnight). Nissan has issued a Technical Service Bulletin (TSB) on this issue.

There is a check valve in the fuel pump assembly that holds fuel in the fuel line so that fuel is readily available to the engine. This valve fails and allows that fuel to slowly drain back to the tank. The reason you have to crank the engine for a long period of time is that the fuel has to be pumped from the tank all the way to the engine- may take 10 seconds or more.

Once you start the vehicle, fuel is available and since the drain back to the tank is slow, restarting after even a few hours will be much easier.

The repair involves replacing the fuel pump "module" assembly (it's a service kit that contains the check valve mentioned earlier). The fuel pump assembly is removed from the tank and disassembled and reassembled with several new parts. This is a dealer-only repair. Depending on your level of expertise, you may be able to perform the repair yourself, but will have to buy the parts from the dealer.
