Depends if it is oil or fuel. If it is oil, your oil ring on your pistons collapsed, which means it ran warm, and the engine might need an overhaul. If it is fuel, replace the injectors completely, and have the cpu re-mapped.

Sounds like you may have a bad intake manifold gasket, or if its oil, bad tube seals

Did the servicing and tried to start the engine, it will start but its not working well. when the plugs was checked, it was already wet with fuel.


It sounds like it's been flooded with fuel. Take the plugs out and dry them off then put them back in. When you start the car, hold the accelerator/gas pedal down (don't pump it). This will help to remove any excess fuel from the cylinders. When started, let go of the accelerator (obviously :) )

My 2003 jeep Cherokee does not have power and makes funny sound, i suspect the carburator or injectors, what could it be


2003 should be a fuel injected engine. A misfire could cause these symptons mentioned. Check ur spark plugs, if d injectors are part of d problem it could be they clogged ith carbon, service ur injector nuzzles, check n change d fuel filter too. I also advice a look into ur fuel pump working condition, a clogged filter or dirty fuel tank can affect ur fuel pump. Be sure its ok n the pressure s right.

I have a 1999 hyundai accent and the car stalls when driveing it, is their a fuse that controlls the spark for the timming on the engine. We have already changed the coil pack, sparkplug wires and the...


No ,,No fuse controling spark,,Your coil pack on top of motor could be cracked and causeing this or your fuel filter, or fuel pump, you could get a pressure test done to your pump at a garage,Check your spark plugs,change them if you can, change the fuel filter a good place to start,,,,,,,,,,,,Also is there a check engine lite on in the dash cluster? If so go to Auto Zone parts store and get a code scan done its free,,than they will give you a print out of the codes and what needs to be replaced,,most vehecles in the 90,s have or need 02 sensors that control your air fuel mixture,,,were talking gas mileage here.

Puff-puff sound comes after fuel pump repaired/cleaned !!!


It can happen some times their are few possibility for such problem to happen a few day ago we had see such problem in Hyundai Santro Xing this sort of problem can happen due to
1.Failure or less pressure flow from the Fuel Pump motor which is located in fuel tank.
2.It can happen due to inflated fluctuated current supply from Ig Coil in simple term Ignition Coil
3.It can happen due to faulty spark Plug where it time to need to change those faulty Spark Plug while Changing those spark plug do go for spark plug such a NGK or Denso this both company Spark Plug are or Good Quality they give your car the better performance, Mileage fuel economy efficiency .
make sure that if you are replacing Ignition Coil then better replace 3 things at a time Ignition Coil, Spark Plug, & Plug wire set.
& do remember to replace Spark Plug at every interval of 10000.Km.
in this case you better consult to an authorized Hyundai or KIA motors service workshop where your problem will be sort out hazard free.

Ok i have a 1999 hyundai accent wont start changed fuel pump and it started ran very bad very! turned it off wouldnt start back up again checked spark plugs no spark and no power going to fuel pump we are...


Changing the pump doesn't affect the spark so lets start a that the beginning?? Why was the pump replaced and was it running fine before changing the pump? Also plugs could be fouled as well but if it was working fine before the fuel pump it will be fine afterwards if getting gas and the fuel pump was the problem., Also how did you verify no spark??

Car want start


The mechanic should check on the fuel filters , the spray nuzzle and the fuel lines . The fuel filters "the primary and the secondary filters".If these filters are dirty fuel are hard to enter because the dirt keeps on blocking the fuel to pass or go to the engine . The spray nuzzle if it is also dirty then the fuel also is hard to spray or to pass for engine compression. The fuel lines if the fuel lines are worn out or have leak then it should e replaced. These spare parts if they are been worn out or dirty they should be clean or some times be replaced . for good so that fuel will not spill too much on the car.For these problems can cause fuel leaks or engine problems it will result to engine lubrication.
