Title: Wierd Starting issue, wont start off for 5-10mins
Post by: mgrolimund99 on 28 January 2008, 15:37:03

Thanks to everyone re my gearbox issue, new selector switch has resolved my issue.

But now have a strange issue where if I go somewhere and turn the engine off for a short time, it wont start again! leave it for about 20mins and it starts...... Breakdown people thought it was an immobilser. But I dont have one i thought. Alarm at least was torn out by the police, (x police car not a raid on my car!)

Did it again the other day at blockbusters. Wouldnt start, would kick into life. left it and then started no bother. wierd....

Sounds like possibly a failing crank sensor to me. Read the fault codes from the engine ECU and see what you've got.

Just a thought, when you say it won't start, it is turning over on the starter motor, but just not firing, correct?

.. or is it failing to turn over completely?

i.e. cranking or just clicking?

Do a paperclip test. Or bring it up to brackley for a chat with the tech2

spare sensor? I only just heard that it existed. How much these things cost then? roughly?
Might take up on that offer 'TheBoy'

Mine was roughly 40 quid on trade club. Might find them slightly cheaper on ebay but make sure you identify which one your car needs as there are a couple of varieties.

However, get the codes read first. It just may be something else.

As per PM, happy to tech2 it, but a paperclip is cheaper if you want to try yourself ;)

If you have a 19 stored, get a new cranksensor.  Plastic type (likely for yours) about £40 + VAT, metal type about £20 more

this look like the one? :question

It could be.

The shape of the electrical connector is the key.....so check the one on your car first if you can.

I broke down during a postal strike and tried to claim off them as if they hadn't been so lazy I would had my crank sensor a couple of days earlier.

(Bought off Ebay but special delivery failed)

Ok, so I have the paperclip test details and the post about crank sensor. Can I just check the plug that I need to check whether its oval or square is under the panel I need to remove by the window wipers?

Plug a bloody paperclip in!

I should add, mine went at about 90mph on some European road....    ...generally, leaving to cool for 30mins or so allows you to continue until it warms up again.

But a paperclip will prove it ;)

If you're really unsure about the paperclip test, I'm on oxford later this afternoon, I'll swing by and read the codes out for you... :)

Shame we don't have a crank sensor, wouldn't take me ten mins to pop it on if so.  PM me if you want a hand..

Hi, thanks for the offers people. May need help if indeed sensor needs changing. Done the paperclip and it seems to be coming up with number 9.

ie it flashes once, then twice, then nine times.

Whats that then?

Should flash 12 (1 flash, short pause, 2 flash) 3 times, before moving on.  Sure you are not getting a 19 in there as well?

Title: Re: Wierd Starting issue, wont start off for 5-10mins
Post by: mgrolimund99 on 03 February 2008, 10:24:27

no its definately 9. been in the car for ages counting the flashing. yes it does the 1,2 thing a few times then does 9 times.

Dont have my list of codes handy, will try to remember to check later.

Title: Re: Wierd Starting issue, wont start off for 5-10mins

what comes after the 9?

Title: Re: Wierd Starting issue, wont start off for 5-10mins
Post by: mgrolimund99 on 03 February 2008, 12:39:12

okay, well it seems to be turn ignition on:

2

9

9

!!!!

i thought i was going to get 1 or 2 flashes then 19 to indicate the issue but i guess you add them together. So assuming that then its looks like it could be 19. ie 9 + 1 + 9..... but im guessing... [smiley=embarassed.gif]

Title: Re: Wierd Starting issue, wont start off for 5-10mins
Post by: mgrolimund99 on 03 February 2008, 12:40:05

but to be honest, it quite tricky to write it down and count it all the same time.... :o

Title: Re: Wierd Starting issue, wont start off for 5-10mins
Post by: Marks DTM Calib on 03 February 2008, 14:20:59

19 is crank sensor.......but then we have been saying that for quite a while now  :y

Lol.....imagine what it would be like for an immobiliser fault......144 flashes!

Yup, crank sensor as suspected :y

In Maintenence Guides is a guide on replacing, and a new route for cable.

Post by: mgrolimund99 on 08 February 2008, 11:48:30

crank sensor replaced, and fingers crossed its still all working. Im afraid I chickened out and got my garage to do it though when I saw when the sensor was located right at the back of engine. also max'd my credit card to lower the car at same time! but dont tell m'wife... ;)

broke down on way to garage though.... ended up having to be towed to the garage. :-[
