Have your fuel pressure checked it maybe your fuel pump or a bad fuel filter or fuel regulator

    Fixed!!! no fault codes stored and would start then cut out with puffs of white smoke and strong unburnt diesel smell like it was fuel related(Sometimes it would even run but not rev up correctly).. Checked fuel system and crank sensor (OK) but disconnected EGR valve 2 pin connector and started first turn!!Removed EGR and cleaned (Runs perfect) but replacement ordered.. Hope this save´s someone time and money :) !

SOURCE: 2005 Hyundai Tucson jerking violently

mirandamcl,

I just took my 2006 Tucson in to have this fixed. It was simply that that hose from the air filter was not clamped on tight. That was 2 days ago, no more problem.

SOURCE: Hyundai Sonata 2000, sluggish to start only after fueling

Purge control solenoid valve is suspect. After refueling, the charcoal canister can become 'saturated' and this valve (if stuck OPEN) sucks air through it and can draw raw fuel into the intake manifold creating a 'flood' condition.

SOURCE: hyundai tucson 2006 start overheating out of

Waterpump, seems like a likley culprit. Your Ac compressor belt runs over your water pump. when the ac is on it puts more load on your engine , your water pump may be defected and not able to handle the extra load.

Car running rough at random when accelerating and also idle drops suddenly when slowing down and often completely stalls out when I stop. Smells strongly of gasoline when it stalls/almost stalls but I


This could be a lot of things. one of the tests that you need to run is shift it into nuetral when you are stopping and see if it still drops RPM and wants to stall. This will eliminate or conclude that it is a transmission issue. If it is still doing this then it could be a vacuum leak or fuel delivery issue.

The engine is running very rich that is why the exhaust is emitting black smoke. The engine needs a tune up so the air fuel mixture is correct.
