Title: No power too Coil
Post by: GolfMadnesS on 08 March 2006, 23:01

Hi,

New here,great site and have been reading for hours :laugh:,I bought my 98' 2.0 Cab coming on for 2 weeks ago now.

When i viewed the Golf it was running real bad,i put a set of new plugs in and patched the well known knackered breather pipe,then it seemed almost perfect,i replaced the offending breather pipe and cleaned the attaching areas :smiley:,thought all will be fine,then in the following days after pipe being fitted,i was having the low revs and dieing at junctions and when dipping the clutch,hence me coming across this site :cool:

After reading i thought no problems,ill go out this morning and get some carb cleaner and clean out the throttle body,but the car wouldn't start :sick:,i checked for fuel on the plugs(they were wet),then checked for a spark,no spark at the plugs.

It seems there is no power coming to the Coil(checked with volt meter),so i think the Coil maybe fine,im starting to think the Immobiliser has decided to kick in,i removed the battery power,Damn bad move no i get the inicators flashing allround as if the alarm has activated,but with no siren :laugh:

I have only one key and no key for the alarm overide?,i have replaced the Ecu relay no30 i believe,the fuel pump seems to be working fine when ignition is switched,had it Vag-Com'd some days before it dieing on me this morning,2 faults came up temp sender and Mass air flow.

Temp sender has been replaced,im putting the mass air flow down to the sh** that was in the TB,i need to find out someway of either
by-passing the alarm and immob,rang up Main stealer they are not willing to help me out on the wiring diagram front,i guess they want some labour out of me :shocked:

Im gutted ive got a 85 Mk1 Gti Cab with like 160k on it and its never let me down(but had its faults),this mk3 thing had got 70k on it and im having a right nightmare,thought the mk3 was a good wise decision to get as a family car and for comfort value :cry:

Sorry for the silly long post,i have read as much as my head can take i need help,i have searched high and low for some way of getting round the immob hoping this is my problem,i think one user(golf-vr6) on here has had the same trouble and a fellow forum member(not active i believe) done some sort of  by-pass wiring.

Again thanks for any replies inadvance,any help is better than no help :cool:

It sound to me like you need to replace the Mass air flow meter.  Or maybe the coil has packed up!!!!! :sad:   Both aint cheap unfortunatly.  It might be best to got an auto lecky to have a look before you spend any more dosh on parts though mate.

Hi,

Thanks for the reply,i believe the Coil could possibly be fine,untill i can get power to it,i cant be sure its dead.

for the mass air flow spoiradic? fault,i believe that could be a number of things,not just the air flow meter,will find that out in time :laugh:,just the car was fine accept the low revs at junctions when dipping the clutch or light braking,then i come to start it yesterday morning and nothing :undecided:,just turns over with fuel getting to the plugs and no spark.

I think someone mentioned the factory alarm/immobiliser should cut fuel and spark?,also i belive it to be factory as i think they started fitting them on 98 and onwards models?,all this im not 100% sure on,ive just read most of it on my quest...

I'm hoping the immobiliser has caused this and is just cutting the power to the Coil,then to add to my stress i have the silent alarm going off when i connect the battery back up :laugh:

have you tried the ignition switch, this is a common fault and can cause some strange symptoms.
mine was faulty when i went to buy  my car, started occasionally, then dead then only stage 2 ignition but no starting etc etc. i did post a method of changing the switch without removing the steering wheel somewhere if that helps.

Hi Nitro,

Thanks for pointing that out to me,i hadn't thought of that to be honest,was kinda hoping it was the alarm/immob cutting the power.

I see on a thread you replied saying you managed to use a drill to get round taking the steering wheel off and so on,was this easy enough?,thanks for your help man,think ill head in that direction and hope for the best :cool:

Trip to the main stearlers once again damn at this rate ill be going back to me MK1 for the easy life :laugh:

have u got no power at coil , or out of dizzy lead , mine was same last week a new rotor arm and dizzy cap from gsf for a tenner sorted , pull lead off dizzy that comes from coil and check for spark there .
daz
p.s if anybody is in derby area , i know the mechanic at main stealer , he might be willing to help for beer tokens :cool:

Title: Re: No power too Coil
Post by: GolfMadnesS on 12 March 2006, 10:18

Hey there,

There is no power in the feed/plug too the Coil,so therefore im losing spark before the leads :sad:

Think im going to get a Ignition unit from the sealers Monday,i did try yesterday,but the parts guy had gone early :undecided:

If that doesn't work then ill be tackling the factory alarm/immob :huh:

Still unsure on how to remove and refit the Ignition unit,i think ill try the easiest way first(drill) if that looks abit hairy ill be getting stuck into removing the Column :cry:

good luck , and i hope it doesnt cost to much :smiley:

i hope you get it sorted without too much hassle, the drill method did work fine for me, and it is still ok ;-} you just need to take a bit of time lining up the drill, there isnt much to damage if you get it a bit wrong, good luck.

Hi, had a similar thing on my mk2 when i first got it, had two wires coming form the dizi pack in to dash area :shocked: looked into it the guy who had before me had it wired up to the fog lamps  :rolleyes: or an extra foglamp switch! Job was a good one too, had no power up to coil or amp until I shorted wires together :smug: been great since now got an alarm to do the same job but with a bit more control :grin:
this may not help but thought i'd share it just to be sure :wink:
good luck  :smug:

Hey,

I rang the main stealer up today,the main guy for parts at my local dealers says that the Ignition module is on the same unit as the Transfer something or other :undecided:,the price for unit is around £80  :sick:,he says the Mk2 had a seperate Ignition module,Mk3 has a combined unit.

Think im going to have a chat with a local Vw specialist since its not worth changing the complete unit when i cant be 100% sure it is that,was worth a shot for the mentioned 20 quid module.

Hopefully he can help me out with not too much cash involed,i think i might invest in a Bently manual for future problems...

dont know if am answering the wrong bit here but just to avoid confusion, i was talking about the switch in the column not the ignition module itself.  :tongue:

Nitro,

Crossed wires i think  :laugh:,ive been reading all over the place and getting myself mixed up i think  :shocked:,right i know where we both are now...

Will give it a try asap,will post back and let you know how i get on,then if it fails i guess its time to pay out some labour charges to get her sorted.

Title: Re: No power too Coil
Post by: GolfMadnesS on 14 March 2006, 10:18

Damn,

Just read through the thread on changing the Ig Switch,and noticed a guy saying he lost signal/feed to the stereo then a short time after his car failed to start.

Why did i not "click" when reading that before...When i got my car the stereo was not working,thought it must be a fuse,but it had lost its live...wired a permenant live up,then a few days later my baby has failed to start.

This is looking very promising,thanks Nitro fingers crossed i should be motoring again :evil:

*Edit*

When changing the Ignition switch,will i need to mess around getting things reprogrammed?,Nitro did you have an alarm/immob present on your car?.

I believe i got a factory alarm and immobiliser fitted as its all seems to lead off into the ?lume,theres some mention of the key needing too match the ignition so that a signal can be sent to the Ecu,will this mean i might things worse changing the switch?,im getting abit wurried here :undecided:

Title: Re: No power too Coil
Post by: nitro on 15 March 2006, 12:43

nah, you shouldnt need to do any of that reprogramming shi@. my factory alarm/imm' is disabled so didnt affect me. but its the switch insert that you want, not the actual lock part i think the number is 6NO 905 865, thats for my Mk3 '92 2E 8V anyway.
the complication in the removal of this fecker is that you are supposed to strip the steering column to do the job. because a 10mm x 3mm self tapping screw holds in the part, and you cant get to this unless you strip the column stalks etc. fecking pain.
have a look at it and see how ya feel about the drill method, or i have heard of people just breaking the old one out. the idea with drilling is to drill through the small plastic tab that the screw uses to retain the part, you will see this when you get the new bit, it will all fall into place  :laugh:
best of luck - it really aint hard, just take it easy  :wink:

it will all come out in the wash

Well fitted the Ignition switch today and guess what yep you guessed it no change :cry:,think im gonna need to get the factory alarm removed.

I just ordered a Chiltons manual for my car as it covers my car and also cars above it,im hoping to get a detailed wiring diagram so i can pull the factory alarm/immob myself otherwise a trip to a well trained alarm fitter to get it pulled and a new alarm fitted :huh:

Title: Re: No power too Coil
Post by: nitro on 19 March 2006, 22:00

feck...  i am real sorry it didnt work, it sounded like the problem  :sad: :sick:
it looks like its goin ta be one of those sloggin it out problems.
just dont loose heart, be extra methodical (make sure you dont miss out anything), dont jump to conclusions and think of the satisfaction when you get it fixed.

the beers are on you when its fixed   :grin:

Title: Re: No power too Coil
Post by: GolfMadnesS on 21 March 2006, 16:06

little update for you :grin:

I managed to get her started yesterday after trying various ways to get around the alarm and immob,got the alarm figured out and disabled and it still wouldn't start,then managed to trick the immobiliser and hey presto she fired up...

Once started it sounded very rough,thought it must be the fact i sprayed loads of carb cleaner down the throttle body and so on to solve the stalling and low idle at junctions... but it didn't pass and i noticed a strange tappet style noise :lipsrsealed:,i had a listen further down the engine and noticed it coming from the dizzy,so changed the dizzy cap and rotor and now its as sweet as a nut and cleaning the throttle body out has worked a treat no low idle or or stalling attempts for me :laugh:

I know i said the new Ignition switch didn't work and that's true,but it has solved a little problem,i believed the switch would help as ive lost the live to the stereo and i believe thats a tell tale sign of an faulty Ignition Switch(as i read somewhere),i had also lost feed to the roof(which is in the same area of lume).

So Nitro the b33r's are def0 on me :evil: :grin:

For future reference to people with alarm and immob troubles i'd have a read and a good search on the VW section of this site for more understanding and tricks around the factory systems seemed to help me might be of use to someone else-: http://www.automotiveforums.com

I think my Ignition switch on my MK3 1.4 CL is up for renewal - getting the same symptoms of no 12v to radio and occasionally failing to start..  :sad:

nitro - how much of the dash around the steering wheel do you have to remove to get to the place where you drill? and are there any fittings like screws i need to replace, or can you use the existing ones?

cheers.

daz.

Title: Re: No power too Coil
Post by: nitro on 30 March 2006, 09:09

sory for the delayed response daz.
just remove the top and bottom shrouds around the column.
use existing shroud screws, the ig' sw' clips into place( or is held in by the wiring plug that goes into it) so you dont need to buy anything really, i cant remember if i said in the earlier thread, but it was about a 3 or 4 mm drill i used, and again check your measurements and angle carefully.

Hey nitro,

Ended up going to my mechanic mate in the end, he had a puller to get the collar off the steering column and once that was off, was just a case of undoing the screw and the switch fell out  :cool:

Radio now working again  :nerd:
