can anyone help. I was driving back from work tonight, got stuck in a queue and my engine just stopped
Fortunately I was only 20 yards from a garage and this guy said that there was no spark and therefor no power coming through the coil, but is there any other reason that there may be no power?
How much is a coil? The haynes manuel looks like it's easy to fit a new coil, but I am worried that if I do get a new coil it might be something else that I have missed.
haha yep tis your coil mate, what car is it? like model? i paid a tenner + p&p off dan barnes (hardhitter) for mine, or they are like £40 from GSF i think. if there is no spark coming through it is the coil. its a ten minute job aslong as you get one thats the same model as yours (mine was a different brand and mounted slightly differently so i had to gaffa tape it to the gearbox as a earth point whilst i drove to get new bolts!)
Not necessarily the coil. Not sure what model you're talking about, but on the Mk3 Polos the hall sender failing can cause lack of a spark (it sends a signal to the ECU to tell it to create a spark), and also the ECU relay packing up can cause this too.
Do you hear the fuel pumps prime as normal when you turn the key in the ignition?
The fuel pump priming will be the noise you hear when all the lights are illuminated on the dash before the engine is actually started. Its kind of a *whirrrr* coming from behind you.
I can assume the fuel pump priming rules the ECU relay out (though best get Andy to ok that first, as he knows wheeey more than me ). That would leave the hall effect sensor and the coil...
I kinda feel a little more confident about it just being the coil. I think I'm going to chance it an price up a coil from an independant VAG parts shop at the other end of town. Already checked on a VW parts web site and waiting for them to get back. The price difference will determine speed of recovery.
sounds like it is the coil to me. if the hall sender fails you'll usually still get a spark but the timing will be way off, which makes it pretty hard to diagnose.
Well, not the ignition coil at all, but a very wet hall sender. Don't quite understand how the hall sensor got so full of water (the rain was really coming down in buckets half an hour before driving), but emptied it out, filled it with grease and now have no problems at all.
Thinking about a replacement though, but would I also have to get a new dizzy?
). That would leave the hall effect sensor and the coil...
