Ibiza conked out, showed battery light but no spark!

They are the symptoms of a crank speed sensor, ive just checked on another site. Exactly what you said above, and also no spark.

However, I have read three members on here with that fault, and each one got a fault code for it on diagnostics. (G28 speed sensor). So it really needs reading. I use a fault code reader which cost £30 (autel) off a popular auction site, or its about the same cost at any garage. With a reader you can reuse, which is handy. Its easy to use the socket is usually beneath the steering wheel, pull down the compartment and its on the left.

I think its £70 for a speed sensor, so its not cheap unfortunately.

The metal bit on the end of the leads needs to be snug on the spark plug, when I buy new leads I have issues trying to get them off because of this! Also the rubber insulation should go further down the plug ie over it, basically the metal bit that connects onto the spark plug should be an inch roughly inside the lead.

It might be worth taking a lead off a plug, sticking a screwdriver inside and resting the screwdriver on the engine so the shaft leaves a small gap. Then do the same test as with the spark plug ie turn it over and look for a spark. If no spark do the same with the lead that goes into the centre of the distributor cap, if no spark then it suggests either bad coil (shouldnt be as it is new on yours!) or that no voltage is going to the coil (likely).

After above its very much sounding like the speed sensor, however if youre feeling mechanically minded you can check the coil using this link;

Success!!

Hiya,

Got great news!! It's fixed - turns out it was the connections to the computer. Don't know why but seat decided to put the ecu under the windscreen which is so stupid!! All the water goes down the windscreen and into the little part where the ecu is so it's constantly sitting in a swimming pool no matter how hard you try to keep it dry...

Had the connections cleaned, wires pulled out then cleaned up and sprayed WD40, loads of gunk/carbon/water/whatever down them.

The only prob i have now is that when i first turn the car on i have to rev it a bit for a while or else it conks out... i think there's still some more cleaning and degunking to do yet. But once the revs get to 10 then it doesn't play up again and i'm off with no problems.

Hope the idle thing will sort itself out eventually though!

Thanks for all your help - especially Rob cause what you said about the wires was right, one of the spark HT leads wasn't working, fixed that and car doesn't hesitate now.

If any of you lot have the same problem then check the ecu wires and clean the connections and keep an eye on the hole where the computer is to make sure it's dry or else your car will conk out too!

its good you found out the problem and solved it, it feels good doesn't it?

the idle problems may be down to air box/hoses blocked up, my sisters Audi A3 is the same at the moment, so clean them all out i'd say!
