On the wife's 2.2..
She will get in, drive somewhere, shops etc, get in start the car, which starts, but then cuts out leaving all dash lights on, eml flashing (sometimes, she is unsure).
The car then wont restart for anything between 30 seconds to 15 minutes.
Any ideas?
My 1st thougt was immobiliser related, we swapped keys to no effect.
-
Not as common on the 2.2 but I suspect the crank sensor.
Other thought would be a positive feed shorting to earth once it gets warm.
-
Bit more to add, helpfully very intermittent!
My old Astra (x reg from new) also always did something very similar all its life, never got to the bottom of it, but it wasnt mine so didnt really worry me much as it was very occasional.
-
cam sensor?
-
There the same symptoms as Taxi Drivers and Auto Addicts Cam sensor failure....
-
Sounds like we have a starting point!
Any chance of the part no and price
and where may I find it to change ;)
I have spanners, but they are very shiny and new ;)

Watch this space for a How2, i am doing my cam sensor tommorow!
Part number: 90520850
Think he said £68 including VAT, but i am taking TB's TC card ;) ;D

cheers fella ;D

eml flashing (sometimes, she is unsure).
Flashing EML is immobiliser normally - maybe an issue with receiver in ignition barrel?

Thats why I went for the key swap, but strange that it does start, all be it briefly though.
Dont know enough about exact behaviour to know if that is normal for immobiliser or not.
-
I believe that the car will start, but if correct signal not received within seconds, it will stop. Maybe someone can confirm?
Still a good chance its the cam sensor though ;)
-
Correct, the immobiliser system is a slow protocol hence the car will start and after a few seconds if the ECU has not received the pass code it shuts off fuel and ignition.

looks like we have 2 avenue's worh starting on.
Now have others with dodgy cam sensors had a flashing eml?
after this occurs should there be a readable code, despite no eml permanantly lit?

I've never had the EML flash, and my cam sensor has been failing since the summer ::)
Only problems i had was it would take a lot of cranking to start in the summer, if it had just been run. Usually when it finally burst into life the spanner light was on.
Any one with tech2 near you Jim?
-
yep, 2 very local places have it
am borrowing a generic code reader tomorrow to see if there is anything

I can't remember the fault code the Tech2 gave for the cam sensor :-/
-
I dont believe its cam or crank sensor....a 2.2.....possibly 2.6/3.2 will start with them disconnected.....tho havnet tried disconnecting both of them together......it struggles...prolly 5 secs of cranking but it will start.
Sounds like imoboliser prob if the EML is flashing

That'll be P0340......you should remember by now Tunnie.....TB's cleared it enough times for you ;D

I know thats why i was ashamed! :-[ - I could vagiley remember it, but didn't want to post incase it was wrong
-
Aye, P0340 is cam sensor....
Can't remember the immobiliser code on the 4 digit systems, its 145 on older ECUs...
-

These cam sensors on 2.2's have a lot to answer for, but this does sound a bit more than that.

Sounds immobiliser due to flashing EML, but I would never rule out cam sensor on a flipping 2.2 >:(

Niether would I......

and at £50 TC, £66 retail they aint cheap either.
Watch this space for a how2 on the cam sensor ;)

I'll be watching with interest to see if you do it with aux belt off....the 'correct' way, or the shortcut way ;)

Do students ever do the 'correct' way ;) ;D

What you have to remember is that 'the wife' thinks it might be flashing which in a womans case means, 'no probably not, didnt notice, not my colour' ;D
