Yet another questions about starting

[DrR]

I've searched, but my prob seems to be, car starts cold fine, starts warm fine, but if you say drive it for ages, then turn of engine for say 30 seconds while nipping into a shop, it won't start, have to do a few attempts.

what does it do when you try and start it, does it sound like the battery is low (i am not about to tell you its the battery thats gone) i have a simliar problem and the only way i solve it is by getting someone to push it when i pop the clutch and make the engine turn over, and then wala its starts as it would normally. Edde was telling someone else a tip that you should leave it in reverse and rock the car round a bit but i havent tryed this myself

Coil pack on it's way out? lambda sensor? I had mine replaced they always seem to go. Don't put up with it because it's very fixable.

 

[DrR]

Car turns over, just keeps turning over, then i stop trying, and try again and she fires up.

 

[DrR]

Is the lambda sensor the thing that goes in the Exhaust?

 

[tommyboy]

yes iirc I had coil pack and lambda sensor replaced on my mk2 and it solved the problem. also I started to use my spare key as a low battery in the key fob can cause immobiliser problems

 

[Neal 182]

I say TDC for is as well but get the codes read first

 

[DrR]

How much was the coil pack and sensor? It's not really a problem as my car only ever does long trips, not much driving like that at all.

Try another key...see if the issue is key related...if not, at least you can take that out of the equation. I have 4 keys for my car...3 have immobilisers/fobs...the 4th is just a copy because I had my ignition barrel replaced under warranty. Out of the 4 keys, I can only start the car with 1...the other 3 don't start the car!!!!

Wouldn't ty this on a DIC try bump starting an 18.1 to 1 CR engine isn't easy.

Not sure what tip that was for sounds like a trick to knock the starter motor around so it works.

Does it start and sound like its got the power to start? Most likly its the TDC sensor acting up.

Coil packs £40 or so

TDC sensor is now a new design with a new wiring total cost is £50 £25 for the sensor £25 for the loom much better design.

 

[DrR]

Yeah has the powrer to start, it turns over fine. Just doesn't sound like it's "firing"

TDc sensor sounds most likly problem.

 

[Batman]

i had this problem took more to start when the engine was hot, i've replaced the plugs and coil pack and its firing everytime but still not straight away when its warm so i'd say tdc sensor, i wanna change mine but about baffled on how to wire it into the loom?

 

[DrR]

Lol i'm just not gonna bother.

 

[Fletcher]

Mine used to do this all the time, she would start fine from cold but once warmed up i'd have to try a few times. Mike a Rentech sorted it out ages ago, and she's been fine ever since.

lol so what was it?

 

[Fletcher]

Not to sure, no new parts were needed though.

 

[Renault_Boy01]

Yeah this happens to my car to... as with Fletch123 mine also only doesn't fire when its warm

 

[sean]

99% tdc sensor. when you now purchase from renault you also get a new connector block and loom with 2 heatshrink terminals which needs to replace the connector off the origonal
loom. done lots of them.

Low battery in the key cannot cause immobiliser problems. The RFID chip in the key is a passive device until it is placed next to the reader then it receives a charge from the RF emitted by the reader which charges a chip capacitor which powers it up and it transmits the coded signal back to the reader.
It will work even if you take the battery out of your key, that only powers up the remote locking transmitter part of the key.

I would start by checking the fuel lift pump and the return pipe.

 

[DrR]

Decided to finally fix this prob the TDC is the thing sticking out the top of the cat?

 

[Dave@Rentech]

if you can get it to a garage for a diagnostic thats the best thing to do, if not try the tdc sensor, cant say it will fix the problem but very common fitted two today.

For the price i'll give it a go, and the diagnostics thing would cost me, where is the TDC sensor located?

 

[Da]

iirc TDC sensor isn't in the CAT, it's on the right hand side of the engine down just above the gear box.

 

[Dave@Rentech]

The TDC sensor is above the gearbox its a butterfly shaped sensor. i believe you may have to remove the air box to get to it on the sports

 

[DrR]

Ok thanks, i'll get yozza to sort it when i have me service in the near future
