Diesel Getz CRDI 1.5 2004 - Engine Headache!

[Lyndiesel]

Hi Everyone

I have a Diesel Getz with 240 000km on the clock, regularily serviced, that has never so much as hiccuped or had any problem until about 3 months ago. A collegue was driving at aprox 120km/h on the high way, when he says it gave a mild jerk, then about 2 minutes later just stopped. He reported no overheating indication, etc.

It has not run since - now R 17 000 later at my trusted mechanics who have regularily serviced my other diesel pickup - and who have also been in regular contact with the Hyundai Mechanic at the local agent.

Every sensor has been checked /replaced, new rings were fitted due to compression loss. One injector has been replaced, injectors, tested, high pressure fuel pump chacked and overhauled - relays have been replaced. glow plugs replaced. It has been on 4 diagnostic machines - and still no start or run after the repairs. The diesel in the tank has been replaced, the fuel pump in the tank has been checked. Everything seems to be operating and checks out according to diagnostics - but no start or run.

We are at wits end! what are we missing -any ideas - similar experience?

Thanks !

Sorry to see that you are having this kind of problems. Since you say everything has been tested (sensors, DTC codes, etc) and nothing has been detected as defective, and from the original situation when this happened (engine died all of a sudden), I presume whatever is wrong is not ECM related (it is not detected or controlled by the engine control module- "computer").

Under this circumstances, "old school" mechanics should be applied. This means, going back to basics:

1) Unplug and remove all the engine control wire harnesses that connect to all sensors. Check every single plug for corrosion, bad or broken contacts and all wires for possible connection faults.

2) Have every sensor removed and checked according to working specs (not through scanner diagnostics, but through actual resistance and conductivity tests in each individual sensors.

3) Remove distribution cover and check distribution chain/belt alignment.

There are many other things that can go wrong and cause this situation. The attached file is the troubleshooting guide to follow up. Hand it to your mechanic.

Let us know your findings...

Just a quick commente - I had some issues with my Getz 1.5 CRDi 2004, my mechanic couldn't find out what was wrong. THe engine would not start, I had the airflow meter changed and a bunch of other stuff, the diagnostic machine could not find any faults. In the end we found out that the butterfly valve where the air goes into the motor, was full of soot and was stuck on closed. After I opened it, and got the engine started, I sprayed some carburator cleaner in there and gassed the engine up a little inbetween, thus cleaning the soot from the valve. And I haven't had a problem since.

Check the throttle housing for carbon build up. Then if it still will not start you should look at the immobiliser.
