Only starts once

[S2Coupe_Nic]

My car is playing up...any ideas?

I can run her once but then if i turn her off she wont start again for about an hour.

She turns over but does not fire.

does this sound like a 'car' fault or a toad alarm fault

Thanks

Nic

someone suggested fuel pump relay...but couldnt really see the logic

[S2Coupe_Nic]

ohh sorry, 3 posts, keep remembering things, so amateur.

she starts every time, again and again when she is cold.

hall sender failure i'd guess.

Coolant temp sensor?

vag.com the car and see what codes it come up with ..save messing about with trial and error , this should be logged as a fault on ECU

Sounds alot like the hall sender.

Hall sender!

Classic hall sender mate, I had it get it changed before it fails and it won't start period.

Agreed on hall sensor... the LED test is best way to check for sure - across pin 2 and earth... should see it pulse every other crank rotation. Without that signal the ECU never generates a spark - it will turn over on the starter until battery is flat.

So I think....it may just be.....well.....the Hall sender?? ....maybe?

Thanks all as always, having it vag-com tested on monday, will post the results

I've had this, was the crank sensor braking down when it was warm, car would only start once when cold - argee hall sensor is another fav

Hall sender doesn't always throw a vag-com code BTDT
