Title: Urgent help needed!!
Post by: tobybrennan on 26 August 2009, 14:58
well was driving around a round about yesterday and my car started juddering and losing power (quick)
erm i managed to get into a bus stop just as it cut out, all the electrics still work so not battery!

But now the car will not start at all. But when the ignition is on the oil light flashes! is that normal? (silly question i know)


originally we thought it might be petrol, tried that no success.
just need to find answers, as i need the car for work and what not.

Fuel Relay, ECU Relay?

And no it is not ment to flash. Just check that your oil pressure sensor is connected.

Have you checked it has oil in it?

Do you have oil in it?
Any funny smells? (cue fart joke) any smoke?

if you put it in gear and rock the car back and forth is there any resistance?

well i only topped it up with oil the other day and oil changed it 3months ago
soo oil level seems fine i cant see where all the oil would go cause there is no marks outside my house:)

erm funny smells, well when it cut out last night, i opened the bonnet, and yes it did smell a bit eggy

can you pop off you timing cover (top half easy) and see if your belt has gone?

I take it you've tried to turn it over since it cut out?

erm my petrol just shot up, before it was near empty!
and all my indicators are on, not flashing, just on!

You have electrical gremlins! ECU?
Title: Re: Urgent help needed!!
Post by: MK3TDi1996 on 26 August 2009, 15:30
indicators might be the relay actin up (it's the ridiculously difficult one to reach on the far right) then again i could be barking up the wrong tree.

Fuel and ECU relay's were already mentioned so it might be time to have a look and see what condition your relays and indeed fuse box are in.

Have you tried a bump start yet?

Post by: tobybrennan on 26 August 2009, 15:37
no i havent, do you reckon its worth a try?
Title: Re: Urgent help needed!!
Post by: Len on 26 August 2009, 15:53
Got any mates with same car? If so swap the relays.
If its not that then you need to get it checked on a vagcom.

Have you got an aftermarket alarm/immobiliser?
Title: Re: Urgent help needed!!
Post by: tobybrennan on 26 August 2009, 17:43
not that i know of no!
but it could be something to do with the alarm and immobiliser
as i know it was an extra when the car was brand new
Title: Re: Urgent help needed!!
Post by: Adam on 26 August 2009, 17:47
Get it plugged into vag com.
Title: Re: Urgent help needed!!
Post by: tobybrennan on 26 August 2009, 17:48

Title: Re: Urgent help needed!!
Post by: Adam on 26 August 2009, 17:49
Scans for fault codes. See whats gone wrong, can be missleading sometimes thought.

Pull out king lead and rest it on the cam cover with screw in trode so it can arc across gap and turn car over, you need to see a spark
Title: Re: Urgent help needed!!
Post by: tobybrennan on 26 August 2009, 18:20
king lead being? sorry im clueless:)
Title: Re: Urgent help needed!!
Post by: Adam on 26 August 2009, 18:22
The long lead from the coil pack to the distributor.
Title: Re: Urgent help needed!!
Post by: tobybrennan on 26 August 2009, 18:34
so when i try to start it, there should be a spark from distrubutor?
what if there is?
Title: Re: Urgent help needed!!
Post by: Adam on 26 August 2009, 18:36
Take it out of the top of the distributor and do as VW BUSH says,

If there is its not a coil pack.
Title: Re: Urgent help needed!!
Post by: AudiA8Quattro on 26 August 2009, 18:38
Mk3's didn't have separate coil pack, there is a coil and a dizzy.
First unplug no.1 ht lead, check for a spark.
If there isn't then unplug the centre lead in the dizzy, check for a spark.

Post by: Adam on 26 August 2009, 18:40
Sorry I ment coil.

Common on Mk3 for Coil to go like this, first thing to check if your car dies
With power and Petrol ok

Post by: tobybrennan on 26 August 2009, 19:05
well the main lead out of the distributor has a spark and so does no.1 ht lead:)
Title: Re: Urgent help needed!!
Post by: VW BUSH on 26 August 2009, 19:56
You have spark so now, check fuel system :wink:

Title: Re: Urgent help needed!!
Post by: Mikester on 26 August 2009, 20:23
I reckon fuel or ecu relay. Or maybe crank sensor? Failing that maybe the dizzy itself?
Title: Re: Urgent help needed!!
Post by: AudiA8Quattro on 26 August 2009, 21:43
It won't be the dizzy as there is a spark.
Check for the fuel pump priming next, or crank it over for about 5-10 seconds, remove a spark plug and smell the cylinder for fuel.
