But the Mechanic has not done any thing in the engine settings. what would be the reason behind. He said this is due to the spark plugs. Can i rely on him..please help..

Re: puff-puff sound comes after fuel pump...
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.

sounds like an electrical problem .pump isnt coming on .turn on key listen for fuel pump to come on for 10 seconds then shut off on its own. If you dont hear the pump then its probley fuel relay . next check wires are plugged into fuel pump. lots of cleaning ?? is the fuel rail screen plugged ???? disconnect before rail if the pump comes on next. turn on key check for fuel pumping out line .
I think you are on the right track. It sounds like you have a fuel flow problem and those are the two items that immediately come to mind. I would start with the filter and then move on to the fuel pump if there is no change.
Try to follow wiring from fuse panel to relays etc and back to pump while looking for bad, loose, soft, thin or corroded connections along the way and clean or repair them as necessary to be sure you have a good clean source for current to flow. Any of these in wiring can cause amperage draw to go up, thus causing the fuse to blow. If all that checked out good, then the probable cause is the fuel pump getting worn and drawing too much amperage thus replacement is necessary. If you have a trusted mechanic in the area who can do an amp draw test on the fuel pump wiring harness, that should tell you for sure.
First I would check the air filter, then clean the throttle body, use brake clean and a small brush, clean the opening and open the throttle plate and clean as much as possible on the back of the plate and down in the throttle. start the engine and rev up, spray the brake clean in the throttle, you don't have to use all of it. also do you have a check engine light?
How could the pump failure contaminate the injectors when the fuel filter will catch all debris. Sounds like someone is trying to take you for a ride! Shop around for a honest repair shop,there out there! Have the fuel pump and fuel filter changed and you should be fine.I hate when shops try taking advantage of customers.
Good Luck hope things work out.
What the heck did he think he was putting in the tank? Gear oil is very thick and heavy, so the fuel pump may have a problem as it is meant to pump gas, which is not thick and heavy like gear oil. There was probably some gear oil in the tank while the pump was operating, and it pumped some gear oil for a short time, which damaged it. Insist that the 'mechanic' replace the fuel pump at no cost to you ,and find a new mechanic for future repairs. Good luck.
Clean/Change air filter, fuel filter, air filter, turbo filter. Clean and check EGR valve and Turbo gate. Check the hdi fuel pressure. Open the injectors and clean it. Give it a try and may be you can save 600 euros.
verify condition by spraying some starter fuel in it.it should start and die if its a fuel problem.
if it still does nothing start checking any and all fuses.if all the fuses are good take out a spark plug and verify no spark.
if no spark check the ignition module.
it might be able to have it checked at autozone for free.but you will have to remove it.
