Hmmm, I think it could be immobilser, not crank sensor
Does it have the reddish dome under mirror?
I agree with Jamie Had a new key coded for SWMBO Astra, and that did the same as the OP's car ie start & then die. New chip in the key & it was away.
(I know it's a different setup though on an early infrared alarm Omega)
Thanks for replying! I only have one key to the car, it looks like this
The key has one of those small immobilizer chips in it, it is there, not missing or anything. But it seems to work only when it wants too?
As for the reddish dome, i dont think i have it, i dont have the car at my house right now so i cant check immedietly.
But i do not have a remote locking key available, erlier owners maybe had it, i didn't get one when i bought the car.
What did you mean with the reddish dome, what does it make of a diffrence?
As you said Andy, i have the same issue as you had with your car, when it starts only for a sec or so and then cuts out. But did you ever get it going by just turning and turning until it started and ran just fine until you shut it off again?
This makes me think that my battery may be bad or that there is some ground loose somewhere... What is your opinion on that?
...
i acctually ordered a crank sensor from ebay today, was only 10 dollars. I dont know what i would do without you guys, My next move was to check all grounds or .....
Generic crank shaft sensors often quickly fail
Oh well, i looked into it and it seems that i have ordered the wrong one too? there are 2 different types on ebay.
I ordered the first one of these 2:
10 dollars
30 dollars approx
i bought the cheapest one, thought i could not lose anything for 10 bucks and i didnt realize that it was different models... the screwhole was on the other side on the first one
But i will wait to see if it fits anyway. Thanks for the tip, maybe i should buy a bosch of the right type instead?
