Car starting problem?.. advice appreciated!

Hi,
Can anyone offer any advice on what may be wrong if a Renault Scenic (2000) will frequently not start easily - i.e. the starter turns over fine, but engine does not fire (seems better if you give up for a few minutes then try again - as though it is "flooded")....? It would be great to try some cheap options before resorting to a garage.
Cheers!

Need new plugs?

Could be your battery? Have it checked, HT leads, Spark Plugs also automatic choke could be on it's way out could be numerous problems.

Also does it start ok the second time after you've successfully started it, Or perhaps left it running a few mins and then switched off and started up again?

Plus it's a Renault and their hardly known to be reliable, My advice is get it fixed and sell it.

I thought that, but they were only changed a year ago - should last longer than that (shouldn't they?).

Battery seems fine.. In general it has been a great car (despite reservations about buying a Renault) - but maybe my luck has run out!

Would be worth checking the gap in the spark plugs, i think it should be .9mm :thumbsup:

even is its not that cleaning them up a bit always seems to make my engine run smoother/better

Does it run ok once you get it started? Any misfiring? Funny nioses, Smoke etc

when you put the key in and turn it. Does the little red light in the dash flash or go solid when it does it? Sometimes the immob chip in the key can go wrong and do what you are saying.

IF its flashing the car wont start. If it does it when its solid, its something else.

I know someone who can fix this if you need help. DO NOT BUY A NEW KEY. !!

I have never owned any feeler gauges (is that what they are called) - but may take out the plugs for a quick clean later....

Seems okay when it is running (but still has trouble re-starting even when warm) - no loss of power or misfire. I know the coil things have gone in the past, but then it clearly seemed to mis-fire badly.... unless they could be gradually failing?

I will also check out the dashboard lights when I get back to it later, but didn't notice anything different, cheers.

Thanks for all the ideas.

It is petrol and not diesel yes?
#11
Bit more detail on car:

Petrol/diesel - spark or glow plugs?
Is problem due to weather getting damper (know it hasn't been great anyway)
Fuel okay?
Any problems when running, ie, is battery getting charged etc?
Have you checked if jump start improves staring - means electrics/battery maybe the fault
Does it have choke - manual or auto?
Anything else you may think of

I bet its the immobiliser. common fault.

Petrol car, 1.6 (16V I think)
It does seem to be worse in the damp weather, ie worse over the last week. But still bad even if engine is warm.
Runs fine once it does eventually fire up (but I am dreading stalling it on the motorway!)
Fuel should be okay - supermarket unleaded, but filled up again since the problem has started happening and no better.
Not tried jump starting as the battery has plenty of power - the starter can turn for 10+ seconds at a time without trouble.
No manual choke lever, so assume it is automatic!

Coils usually just go with out warning, If it's running fine once started with no mis-firing then I also doubt it's your spark plugs.

Could be immobilizer chip as someone's already suggested, But more likely Battery, Starter motor or something along those lines.

If not battery could possibly be your alternator, I'd get your battery and alternator checked which is usually free at most car parts centres. Theirs several around my area which offer free checks so assume it'll be the same where your from.

Probably rule out your choke as well although it could be stuck half open which is no good for hot or cold starts.

Possiblythe immobiliser - but it sometimes appears to be trying to start while it is turning over, or 'starts' very briefly then stops again. Also, wouldn't it just not work at all - or can they intermittently fail?

The suggestion of a partially stuck choke seems possible to me, as it does "feel" as though it may be flooding - am I right in thinking that if it does flood, then you can do something (foot flat on accelerator while starting, or similar)???

Certain immobilizer's will still let it turn over it just won't let it start so yes could still be the immobilizer, Although some if not most do prevent power altogether.

On my Galaxy, You press the clutch pedal down to give it help starting, I assume that closes the choke a little or something.

My brake pedal has certain sequences that can do things electronically to the ecu as well.

Theirs certain things you can do to help them start with the accelerator pedal as well, i'e pump once then try starting, But obviously you risk flooding.

Think your alternator is on the way out, its not recharging your battery. So when you start to turn it over the starter motor does all the work.

I found this information from another website

"Starting problems
From Tony Brown: Twice now my Scenic has been a pain to start, especially if by accident you press the accelerator pedal before starting it. Turned out it was the Top Dead Centre (TDC) Sensor each time. Apparently on the Scenic and other Renaults, the sensor collects fragments of metal/filings on the sensor (must be magnetic) which, if not cleaned away, leads to starting problems (sometimes up to 20 attempts before it does start !) It is bolted to the engine by two bolts and is easily removed for a clean up - I used a wire brush, a rag soaked in WD40 and rebolted it back in and the problem went away. It took 12 months to return but a repeat clean up sorted the problem again. A friend took his to a local car repairer and they charged him £60 to sort - they tried to say they had replaced the TDC but hadn't, just cleaned it like I did. See also here on the Renault Forums."

the immob can be intermittent. Happened in my old kangoo van. defo check the little red flashing light. It means that there is something up with the key thats all.

You can get a new chip put in the key which will sort it.!

I think the problem here of course is 'Renault' wouldn't touch em with a barge pole :giggle:
#21
I've browse the web and the most common problem with Renault Scenic's is probably something to do with the key and/or immobilizer.

Thanks shauneco - I have been trawling the internet for ideas but most are too vague. It at least gives me another easy (hopefully) thing to try without resorting to the mechanics. Can't say I have aver heard of a TDC sensor before!
Sort of hoping it is not the immobiliser as I have no control over that...

NB I also still don't think it is the battery or alternator, as from previous experience the starter uses masses of electrical power and drains the battery - my starter will happily turn over without showing any signs of flagging for ages.

Have just bought a Renault Grand Scenic (2005). Great car but it always takes me 2 goes before it will start. Not a big problem but still irritating and does not inspire me with confidence for the bad weather

if it is the immobiliser. you are looking at about £25 to get the key repaired. Dont worry. Check it out and lemme know!

Silly question - does that mean it would be fine with the second/spare key? If it is the key I will be in touch...

yer it could be! - sometimes if the battery goes in the keys, the memory is lost. The car will start most of the time, but fail others. Just chuck in the other key. see if it works!

Fantastic aircanman! Despite all my doubts, and disbelief initially, you were spot on with your initial diagnosis. The red light on the dashboard carries on flashing when the ignition is on, therefore it is the immobiliser intermittently staying on that is the problem.The spare key works absolutely fine, so presumably it is something wrong with the key chip or the key battery. Now I just need to decide whether to get it fixed, or just give the faulty key to my wife!

Many thanks - and could I suggest that anyone else in the same situation as me, who is reading this thread, leaves rep for aircanman if it also saves them an unnecessary trip to a mechanic! :-D

Agree & repped. Although IMO you are going to get a lot more grief from your wife if you give her the fauty one :-D

well thanks. I had a feeling. - I think its something to do with the battery going flat, then the chip not recognising it correctly. Any mobile key man will be able to sort it for you!! Good luck!! Aircanman
