Default Siena1.6 - Strange problem

I drive a 4+ year old Siena1.6 in Bangalore, done 42K KM, last service done at just under 40K KM. Since the past 2-3 weeks I have been having a strange kind of starting trouble. The car starts fine every morning and evening. However, if I try to start it around 1-1.5 hours after parking it, the engine cranks but refuses to fire. Leave it alone for some time (yet to figure out exactly but 30+ min) and the car starts like nothing is wrong. Have had 3 recent episodes of this. No problem re-starting at traffic lights.

Talked to the Sundaram guys on phone but they havent seen anything like this. Asked me to get the car over to check on their engine analyser. Am yet to go.

Any experience or ideas that can help here?

Thanks
Nitin

Yup, had the same problem on my car. It finally directed things to the battery. Got it changed and haven't faced that problem ever since.

Had big trouble on our trip to M'lore. Car started fine in the morn, went to a relative's place and after some time tried starting the car but, nothing. If you let it continue, you'll reach a point where the car wont even crank.

Also, if it turns out to be a battery related problem, replace the battery and get your starter checked by the dealer. (Just to be on the safe side)

What petrol are you using? If normal, start using Injector cleaner with 91 octane at least.
Also, check the condition of your injectors. Tell Sundaram guys to do it for you. They will.. if not let me know.

That sounds real sinister...

Makes one wonder if your idea of moonlighting is a protection racket...wearing dark glasses in that "bling machine" which sports "pimp" sound.

Shan/Amitava: I too had this 'complete failure to start' issue earlier, which was traced to a battery problem. Got it replaced and now I have a 1.5 year old Amaron sealed battery. Isnt this supposed to last for 3 years atleast? Also, the engine cranking sounds OK and it cranks for quite long time. A bad battery wouldnt allow long cranking, right?

Rudra: Have been using Power for the past 1 year and have been quite happy with it. Used regular for 3 years before that. Do I need to switch to Speed?

The interesting thing is the time interval from stop to start. It is the 1-2 hour window which creates the problem. Beyond that, even if the car is stationary for 5 days, it starts fine on the 6th. Verified this 3 weeks ago when I had been on a longish trip away from Blr. If it were a battery or injector problem, this shouldnt be the case, right?

Just wondering.. Could this be a vapor/air lock problem somewhere in the fuel system?

Will anyway try and make the 'pilgrimage' to Sundaram this week and see if they can isolate the problem. Is there any good garage recommendation nearer to Koramangala/HSR?

Thanks

It depends on how often you check the water levels. Each cell has to be filled seperately. Miss one and the whole system fails. Same thing with our battery, it was just one cell that caused the whole battery to go down.

That's bcoz every time you start a car, it sources a lot of power from the battery (equal to the amount of energy consumed if you were to switch on the stereo system for a few hours). So, if the battery is weak, it's unable to recharge itself in time for the next crank.

Try it with your TV remote the next time the cells bcome weak. They perform fine in the begining, then they start fading and finally give up on you. Leave it as it is and try using it the next day, it'll work as if nothing happened.

So then in that case it would be more likely to start in 1-2hours when the batt has had some fresh juice from the alternator, as opposed to just sitting around for 5 days.

Nitinbhag,

Maybe your car is alleric to something (Cars ALLERGIC to Vanilla Icecream!!!)? Ok, just kidding, but follow the link and read an interesting story, thought of it as soon as i read your first post, and then interesting to see that you are considering vapour lock.
However, it is also likely that it is a problem with the fuel or ignition system (obviously ), so start by taking it to the service center and checking the entire system on their diagnostic systems. It could be anything from a loose wire on the fuel pump, to a badly routed fuel line or a shorted wire heating up and then failing the ECU pre-check the next time you try and start up?

cya

He's already said that it starts perfectly after 1-2 hours and not before that. The 5 day statement was just an example to say that after 2 hours of waiting, it doesn't matter how long he keeps the car switched of.

The problem only occurs for the first 1-2 hours.

He said "Engine cranks but refuses to fire". This means the battery has juice. In case of battery problem the engine wont crank.

It Simply means there is some kind of blockage in fuel transmission to the engine. either fuel injector are blocked or elctrical circuit is loose.
