Hi, has anyone has a diesel Santa Fé?
I have starting issues... sometimes I need to turn my key 2 or 3 times so engine starts.
I can hear the pump pushing diesel to rail every time I turn key. Happens whenever I stop... could it be the valve? pressure sensor? not enought pressure? injector(s) high leak? pump dying?

Anyone had this issue? It started litle by litle... and now... always...

Yes, it could be any of those.
Or maybe an immobiliser fault. Is the immobiliser warning light coming on when you switch the ignition on (symbol is a car with a key inside)? Make sure that light is there when the engine wont start. If it's not that's more than likely what your problem is.

Sorry I'm not seeing any images.

An EGR leak could prevent the engine from starting but that usually also causes performance issues too because the boost pressure from the turbo escapes into the exhaust system. How does the car drive once you get the engine running. Does it accelerate normally?

Hi, the car behaves normaly after start. The immobiliser go off after I switch ignition also.
Tomorrow I will go for a Leak injectors test. Maybe there is a leak in one of the injectors... I have to start with something... so here I go...
I will update you.

Hi,

Finaly solved the issue. Its was the fuel pump located in the deposit that died.
Got one used with same reference(it was hard to find...) and today morning got in the job.
It was back again in to the living world.

Thanks for the help.
Stay well.

Odd that you had good rail pressure with a dead pump. Anyway, great to hear it's living again.
Thanks for taking the time to post back to confirm the fix. I'm sure the next guy will appreciate you sharing your experience.

You see, the pump was in a kind of working/not working at the moment the key was turned... but when it worked... it allows working at next stop... but last thursday... died permanently... so it never start again... I realize that because I stop earing the pump when I start the key... that is why I suspect this pump...

Glad I did it. Hope this can help more users.

Thanks
