I recently bought a 2ltr diesel 2003. It started ok when I first bought it but when the cold kicked in recently I have been having starting problems and I can only start it with easy start. I have had the glow plugs changed today but it has the same problem so was not that.

The key fobs also never worked when I purchased and have changed the battery recently. It was about this time that the cold weather settled in and I had problems starting so I am not sure whether it could be that or it is coincidental. I guess I am suspecting some kind of immobilizer kicking in and stopping the fuel. I think I also had it cut out on me once but it may have been that I stalled it as it was pulling of at a roundabout - felt strange at the time and had a little trouble starting it.

The car has problems in starting up on its own whether it is cold or warm.

This is doing my head in and cannot keep using easy start.

Please can anyone help

Did you try changing the fuel filter?

Hi thanks for the reply, yes the fuel filter was changed today as well as the oil as I wanted a basic service done as well - I was sure that it was only going to be the glow plugs.

My mechanic thinks it may be injectors or a pump problem. May turn out to be an expensive purchase.

Any other suggestions would be welcome.

Has anyone heard of the Santa Fe's immobilizer causing it not to start but is ok after easy start. Sounds strange but I read another post on another forum that suggested that this happened to another person.

I am from the UK if that helps. The car is currently sitting outside, as i drove the car home from the mechanics without them diagnosing the problem - it cut out on me twice and now the 'Check' light has come on.

I guess a visit to the dealers is necessary.

Has anyone heard of an immobilizer system that cuts the fuel intermittently - I still have a hunch that it could be something to do with putting new batteries into a key fob (which now doesn't work at opening the doors or alarm now). It was at this time everything started going wrong (the cold weather had also started coming in at this time.)

Am I going mad?

Hi,
I just bought a 2003 Santa Fe and had a sdimilar problem although it would start when cold it would then cut out, I had the airflow sensor changed and that seems to have improved the problem.

I'm speaking from total ignorance here because I've never owned a diesel engine vehicle, but I'm wondering about something.

When I was in the Air Force and living in base housing in a cold part of the States, we had fuel oil furnaces to warm our units. The base Civil Engineers (who maintained the buildings on the base) mixed a small amount of jet fuel, which is little more than kerosene with some special additives, with the fuel oil for the heaters. It seems that the fuel oil would get very thick and congeal at low temperatures so the fuel pumps in the furnaces wouldn't pull it from the tank very well. When the weather warmed up again, they would come around and put more oil in the tanks so the percentage of kerosene would be less because there was a problem with using it in other than low temperatures.

Is there a diesel fuel additive that can be used for the same purpose in a car?

Paw-paw Don, y'all

Yes someone did mention that it could be that the diesel gets thicker in cold weather - you may have something there.

Hello

I am new in here.
Did not know about this forum before now. If I had known about it earlier I would indeed have posted my problem here.
I have excactly the same problem as described here.
I have a 2002 Santa Fe diesel and real problem with cold starts. As soon as the temperature is below 0 deg the problem starts.
When its not too cold I can often manage to get the engine start by letting it run on the starter long enough for it to start.
It tries to start several times but if I get it run on the starter it finnaly start.
That is if its not TOO cold....
If it gets colder even that does not work.
When it eventually starts it seems to start on 3 cylindres...thats a scary thought.

I have had the dealer look at it several times and first time they said they had an error code from 2 of the injectors.
They were replaced and they were VERY expensive.. !!
Then the next time they looked at the car they said that they now had an error code on the 3rd injector.
It is now also replaced.
So 3 of 4 injectors are replaced.
Still the same problems.

I will let another Hyundai dealers mechanics look at it now and let me hear they opinion.
I thought it might be the glow plugs but I am not sure now after reading the posting here.

Maybe its a computer problem.
Someone wrote in another tread that this was a known problem with the early Santa Fe and it was because the computer was too cold.
They just kicked the computer and the car started.
I will try this tomorrow.

We currently got -20 deg here now.....and the car completely refused to start today.

Please keep me posted....

no member has yet to mention this.........although you may well have had the glow plugs changed, has anyone checked to make sure there is power going to them? and if there is power how long is the relay staying switched on to allow the glow plugs to heat up?

on a side note, you should only use 'easy start' in an emergentcy, once you start to use it constantly your engine will 'need it like a drug junky'
