Golf Chico 2006 1.4 carb model no spark from coil.

[sandheel]

Hi ppl. I have a 2006 Golf Chico 1.4 carb model. The car just refuses to start. Established that there is no spark from coil to distributor. After much labouring it started once and idled. I switched it off and started it several times. It turned one shot. Parked it overnight and this morning it just will not start. Want to know if it is a fuse fault or just old plain TP100 ?????

Not near;y enough info as to what fault finding you have done so far.
There are three items in this system.
1) hall generator in dissy - tells the system the engine is turning
2) Tp 100 amplifies the signal that the hall generator makes as that is too small for fire a coil.
3) coil is the output device for that signal. That is carried via cable to the distributor which puts it on the right plug at the right time.

Which of them and how have you diagnosed it?.

I've checked for spark. No spark from coil to dissy and sparkplug too

[panic-mechanic]

Right....
So based on that you expect us to simply be able to tell you which of the 3 items has failed?.
Let me go check that crystal ball, maybe it started working again.

[panic-mechanic]

Ok - also is there an immobiliser installed?.

Try the following.
Switch ignition on.
While tightly clenching the spark cable from the dissy between your teeth - place a wire with it's end stripped open in the middle slot of the plug from the dissy. IE. remove the dissy cable on it's side and pull the end of the cable into the middle slot. The wire colour is green white on the plug.
Make sure the test wire is long enough to reach the battery + terminal.
Now Very briefly tap the other end of this test cable(that must also be stripped open) on the battery 12v+.
if you get shot across the room from the spark you have just established that the hall generator in the dissy is dead.
If you didn't get jolted across the room you have just established that the hall generator is most likely OK.

Now to test the coil you need to be able to get a wire onto the green wire to the coil - or basically the coil negative. Depending on the coil you might have to strip the wire open a little to be able to turn your test wire onto it.
Again with ignition on and cable between the teeth this time tap the test wire onto the Negative terminal of the battery.
If you get shot across the room the coil is OK and most likely your failure is the TP 100.
If you did not get shocked then the coil has failed and most likely the rest is ok.

ok ok don't clamp the coil lead in your teeth - rather prop it up somewhere that you can see it spark. The rest is correct.

Thanks for the jolts Panic. The lead from coil to dissy tested and it has intermittent spark. Engine turns over when started and dies immediately. I pulled the cubby off, cannot establish where the tp100 unit is. I notice a shurlok box behind the cubby. That's it. The car symbol on the dash is on and will not go away

[panic-mechanic]

So did you do the tests? Did it have intermittend spark on all the tests?
So basically you just cranked it again and gave me your new findings without actually diagnosing anything.

[sandheel]

Thanks Panic. Just finished with it now. It was the transponder unit. Had it bypassed by an auto electrician. The car starts up and runs fine. Thanks pal. Followed your pointers and diagnosed that it was a problem with the transponder unit.

[sandheel]

It is a "shurlok" module that sits behind the cubby. That bugger was factory fitted and the cause of the problem. Its all good now. Thanks again pal Panic

[panic-mechanic]

Hate immobilisers.

[sandheel]

same with me now Gonna install an alarm I understand now lol

How do you bypass that shurlock unit? Im having the same problem

[VAG Fan]

My Fox also has a Shurlok unit and gave me intermittent starter (not spark) problems.

I actually opened the unit and looked for dry solder joints. Found some, resoldered them, and the problem was solved.

How much shurlock costs?

Picture of shurlock?
Can I get a new one?

[Sheea]

Please help

[panic-mechanic]

The shurlock is a coded tp100 module. You install an uncoded module with a short harness you get from goldwagen and then it's bypassed.

How I don't understand?

[panic-mechanic]

yes

Hi there guys

Sorry to jump on the thread.

I’ve got a city golf 1.4 carb that’s failing to start.
So far I’ve replaced the TP100 and the ignition coil and still no luck.
Checked for spark by removing a lead from a spark plug and cranking the engine and no visible spark.

I then thought it’s the hall sensor in the dizzy so decided to test as mentioned above and still no spark... when using a multimeter and the ignition on, I’m getting a voltage on all 3 pins on the dizzy connector which seems a bit suspicious.

The car does have an immobiliser unit fitted. Starting to think that’s the issue.

Appreciate any help

Hi there am testing spark from the coil to dizzy. Spark is coming through but more orange....I'd this normal or is this a sign of weak spark
