The problem is still persistent after replacing the engine and gear mounts and becoming poorer.

As per the so called experts at the service center, the next primary candidates are clutch and fuel injectors.

Clutch
=====
The clutch cannot be diagnosed and can only be replaced and tested. They have agreed to perform a swap check to verify this issue, before they actually charge me for the clutch.

Fuel injectors
=========
They were suggesting that injectors need to be tested and serviced in a center specialized in diesel injectors(Nag diesel) but I was not able to find it online. They said it would cost 5k to test each injector, so that's another 20k. I'm planning on try some diesel additive like STP or Abro etc.
Please let me know recommendations on fuel additives which might improve the injectors and where to service the diesel injectors.

Another update about the late start during hot, the issue is not to be seen anymore. I went for a long ride yesterday and the engine cranked and started as expected. I have no idea, if this is automatically fixed, or maybe it's more than a warm start which was causing this. They also said that the issue could be with the battery at hot conditions.

Current plan is to use the fuel additive for some time, and then test a clutch swap from the service centre.

My gut instinct is that it is the clutch and additives are not going to help you. Do a swap and check

This is quite comprehensive in telling you what to look for http://www.aa1car.com/library/2003/bf50332.htm

Can you describe the problem and symptoms again?

Issue 1
======
About 2 months ago, I was driving to Kerala from Bangalore, and stopped after 200+kms for a quick bite. Then engine took more than 5 scary seconds of cranking till it started.
Same thing after my second stop, but the vehicle always started.
It always cranked in less than 2 seconds while cold.

More recently while driving back from Anekkal, which was like 50 kms, and which took close to 2 hours in traffic, after I stopped the vehicle failed to start after a 10 second crank. After giving it more time, and turning the key between ignition ON and OFF, I gave it another shot and the engine started after a scary 5 seconds.

Now this issue has vanished, and I don't know when this is going to haunt me again.

Issue 1 Symptoms
=======
- Late start/no start at engine hot.
- Issue Not reproducible all the time.

Issue 2
=======
About 1 week after the no-start incident, I had parked at little off-road, and I accidentally had to ride over a pile of bricks, but luckily without any under body hit. Immediately after that the vehicle was shuddering at every gear change after I let go off the accelerator.
At certain times the vehicle would suddenly aggressively shudder when driving at low speeds to numerically low gears.
Maybe unrelated but the shift to first gear from higher gears while slowing down, we need to put a little pressure on the gear stick. This is not there while starting from stop, and only there while slowing down. This issue was there for ever.

Issue 2 Symptoms
=======
- Vehicle shudders at gear shift when completely disengaging accelerator. There is no shudder if a light foot is on the accelerator while shifting.
- Vehicle suddenly and aggressively shudders at low speeds at numerically low gears.

The issue seems to be with your injectors. You can take it to any Fuel injection service center who deals with common rail injectors. If you are in Bangalore you can contact Future Diesel. Contact no. 8050793113

Before doing anything else and swapping parts on a hit and miss approach I suggest you get the ECU hooked up to a proper car specific OBD scanner and get a read out of the codes and as much live data as possible to see if anything is amiss. Takes a few minutes and it can point the finger on the real problem very quickly, or at least eliminate a bunch of possibilities as well.

Good luck

Had same issue ( late starting at times and vibration) with my 2005 Elantra CRDI, I too replaced the mountings etc, but ultimately it was the issue with the injectors. Rs. 800 or 900 was charged per injector for the service. One of the injector had an issue with some parts inside it and for that i had to pay extra. No errors were shown during scanning. Trident Hyundai also suggested for an engine overhaul due to the late starting.

This issue happened around 1.8lac kms and after the injector service I never faced the same issue. The car was sold when the odo was around 2.2lac km.

Thanks a lot for this reply.

I had put a bottle of ABRO Diesel Injector cleaner and I can definitely see a difference, but it's still persistent.
Since the jerking had reduced after using the injector cleaner, I'm more confident that the injectors are the issue.

I have discussed with Future Diesel in Bommanahalli, but it's very far off for me.

Is there are any other shop which does injector servicing around K R Puram, whitefield or Hebbal?

........What can be the possible causes ? Have anyone experienced a similar problem?

Long post alert. But please do read!
I had a pretty bad experience lately and had been following this thread quite closely for clues.

1. Last month on Aug 15th while driving from Hyderabad to Bangalore in my Punto 90HP, bang in-between the two cities my battery warning light switches on. I was doing consistently 130-140+ and I guess these cars do not have a very good electrical protection, and so my alternator conked off! I switched off the car at a toll. But the car never switched back on. I found no help in time so got the car jump started by a cab driver but it lasted only about 15 kms as the fuel pump needs battery to be working. So all I could do was to call up Amaron care and purchase a brand new battery on the highway (even though the old one was pretty perfect! - ~2 yrs old) and luckily it lasted me till the Bangalore airport toll before the car went off all over again. Long story short - I somehow managed to get the car to KHT Yeshwantpur the next day. A new alternator was 15000+labor+tax so I decided to get it fixed.
So, BRAND NEW BATTERY!

2. Got the battery fully charged at KHT and drove to a alternator mechanic opposite Bosch back gate in Adugodi. He fixed the Alternator in 4-5 hrs and charged me 3.5K. Good job I must say (as Fiat will never fix a broken alternator.)
So, WORKING ALTERNATOR!

3. About 20 days later, my car starts showing this symptom. Starts well in the morning. But once switched off, the car doesn't switch on. I wait for 20 min and try again - switches on. And slowly after 4-5 days of running like this my battery dies again. So now I call up Amaron - they take 4 days but confirm the battery is fine. More over, switch OFF voltage ~12.5, ON voltage ~14+, so the alternator was OK too.

I need to add that the starter kit was replaced only end 2016 so I did not suspect the starter either.
Called up a local mechanic and he checked all the fuses in the car (near the batter, under the steering etc.) and confirmed everything was fine. Still no clue!
So, GOOD STARTER & FUSE!

So with a fully charged battery, I now drove straight to KHT only to find out that the symptom was not at all new to them - it was a case of earthing cable cut. So the battery is constantly getting discharged even while not is use! 2 min to diagnose, 15 min to fix, and everything back to normal now.

So guys, next time before going in for a new battery (6K+), new alternator (15K+) or a new starter kit (8K+) - which I am sure most mechanics will push us all to do so, please get the earthing cable checked. Just costs ~1K with labor & tax.
It is possible these guys force us to buy new components only to fix the earthing cable behind our backs!

I've been facing a peculiar problem since the past 2-3 weeks. My car starts perfectly fine in first crank in the morning or after staying unused for a few hours. If I shut off the engine after driving for a certain period of time and then shut it off, it won't start again until the engine cools down. The cranking is stable but the engine doesn't catch.

To me this looks like a possible case of vapor lock or a failed Crank sensor. I read that in modern fuel injected cars the chances of vapor lock are minimal.

I tried a hack that I read somewhere on the internet which is to keep the accelerator pedal pressed while cranking which I guess floods the fuel line getting rid of the vapor. When I tried this trick, I was able to start the car when hot but after 10-15 cranking attempts.

So basically all this points to vapor lock but could anyone here suggest alternative problems that I should get investigated? I'll be taking this in to a garage anyway but am looking for some pointers on what we should investigate first.

[VW2010]

Look at the following

- Fuel Pump Relay
- Vapor Lock
- Coolant Sensor
- Coil

Think of anything related to heat and there could be your issue. Dont change parts as a diagnostics test but try to go one part after another and perform electrical tests.

Looks like a case of ignition module/Coil to me.

[Sutripta]

It's a diesel, isn't it?

[VW2010]

Please ignore ignition coils. I thought it was petrol. But still check for starter motor, coolant temp sensor and relay. These could be the culprits.

[great_guns]

Thanks a lot. I'll start with focusing on these things.

[AbhiJ]

Please also check the fuel pressure (Basically check the fuel pump)
