Poor starting on Sirion

Forum: 

My Daughter has an 03 Sirion 1.3 she's had from new. There have been a couple of occasions when it refuses to start. The last time was when she needed to move up to get space for another car i.e. she just started the engine moved a couple of yards and switched off.
Next day her car refused to start so she had to get RAC who said the Auto Choke doesnt like being started and stopped straight away! He got her going with jump leads and constant turning of engine till it fired, then told her in future to run the engine longer.
I mention this mainly because my Sirion Rally 2 did a similar thing after a short run the other day and it took 3 attempts at turning the engine before it would start.
Can anyone shed any light on this? Cheers.

Wont start Sirion.

The RAC man is correct.
If you start the engine from cold and only leave it on for a few seconds then turn it off.
You are actually leaving the car with the auto choke on. - This floods the engine and it wets the plugs and it wont start.
You can actually take out a fuse to stop the Fuel Injector circuit while you turn the engine over to dry the plugs out !!.
The only other way is to crank the engine until it fires.
This happend to me once. I was told the same by the Green Flag man!
I don't ever start my car and stop it again straight away when cold.
This then avoids the problem.
To be honest If I need to move it a little bit. I just take the brake off and push it !! Biggrin

Mind you I am on the Flat Wink

Poor starting on a Sirion

Cars with fuel injection don't have a choke! This kind of problem used to affect cars from the 70's and 80's with carburators and automatic chokes.

I regularly have to move my other car and my wifes car to get into or out of my garage, so regularly have to start, move and then switch off cold cars and have never had this problem!

The cars ECU (electronic control unit) regulates the fuel using various sensors which measure and regulate the fuel and air supplies and adjust the ignition timing and spark to suit the temperature etc etc. This all happens many hundreds of times a second.

If you have a car which isn't starting well from cold, check the spark plugs, the car may need servicing.

They do have a Choke !!

Maybe it is not called a Choke but it is a Choke !!

It is a cold start system then ok.

If it doesn't enrichen the Petrol when cold it will not start!

If you start and stop straight away it can leave the enrichment on and petrol floods the engine !!

I don't understand your tone at all. If there is a disagrment with what someone says is there any chance of just saying you disagree with a comment.

By the way my car is always well serviced and looked after.

Choke Idea

Hi
The idea about choke is sort of correct, The engine needs a rich air fuel ratio to run when cold which if unchecked will damage the exhaust cat so possibly when stopping the engine after 30 secs the oxygen sensor in the cat may be wet with unburnt fuel then ECU won't allow re-start until fuel dryed off sensor. Possible solution is after moving car before turing off engine hold a fast idle to 2k-3k RPM for 30-40 sec to clear fuel from sensor. Also with reguard to spark plugs I replace mine at 2 years or 20k miles and use NGK, Japanese parts for Japanese cars. Hope this is of interest, Cheers Marcus

Thanks guys

I am grateful for all your replies and sorry about the minor disagreement. Hey we all have our views and it's interesting to read all of them.
Servicing isn't a problem as the car (my Daughters) was serviced by Daihatsu only 2 moths ago.
I kinda like the ideas that the car should not be started and stopped straight away. That's what the RAC guy said and I suppose it makes sense to bring the engine up to some sort of temp. if only for Lube reasons. Pushing is not an option as she's about 4'9" and lives alone so no help!!. I will pass on your comments and trust she will take heed. I might just say its so helpful to be able to ask the question and get so many useful replies. Cheers.

No Worries !!

Don't worry too much about our disagreements.
Clearly a Boshie git - a bit like me at times I'm sure. Biggrin

I have the workshop Manual for the Sirion and the YRV.
The Drivers manual also says you should leave the engine running a couple of minutes when starting in bad weather, before you set off.
The ECU cretainly puts in more juice or less air as the engine automatically raises the engine revs while it warms up.
Whether you call that choke or ECU is really not a problem for me.

Think he must have been in a bad mood. Wink

Poor cold starting in a Sirion

Lets look at the OP again, look at the highlighted text:

“My Daughter has an 03 Sirion 1.3 she's had from new. There have been a couple of occasions when it refuses to start. The last time was when she needed to move up to get space for another car i.e. she just started the engine moved a couple of yards and switched off. Next day her car refused to start “

So the next day the car was ‘flooded’ with petrol!

“so she had to get RAC who said the Auto Choke doesnt like being started and stopped straight away! He got her going with jump leads and constant turning of engine till it fired, then told her in future to run the engine longer.
I mention this mainly because my Sirion Rally 2 did a similar thing after a short run the other day and it took 3 attempts at turning the engine before it would start.
Can anyone shed any light on this? Cheers.”

Again, the car was ‘flooded’, even after a short run?

The symptoms on both cars sound suspiciously like a spark plug problem or a failing lambda sensor. If the plugs are sound and properly gapped, then you may wish to check the resistance within your lambda sensor. When it fails, and they often do on 1300cc Sirions and YRV’s at around 5 years old, it will flag up the engine management light and the code can be confirmed from using an OBD II code reader.

I’m not grumpy or bolshie BobF, I only like to give advice to folks when I know what I’m talking about…..can you say the same? Wink

Like most long term Daihatsu owners, I also have the workshop manual.

Incidentally, you don’t need to be a time served mechanic to work as an AA, RAC or Green Flag patrolman, but it probably helps!

This is Silly !!

Well we clearly have a problem dont we. Sad

Yes I am a timed served mechanic (Although I don't do it anymore)

Yes I saw the message an understood it.

I had an opinion about what it could be.

You had yours. You are clearly very well versed in Daihatsu Problems (Clearly better than me)
I don't have a problem with that.

I don't have a code reader !!

I was trying to make light of our disagreement (These are bound to happen at times).

No worries for me. I will stop here. Help
