[Juddering at low revs]

My mate had this problem with this VR.it was fine when high reving and didnt seem like there was a problem

End of the day it was the fuel pressure regulator.

£65 from euro car parts i think.Try maybe fuel filter aswell though as his was really clogged.

[VR6 Conversion]

Ok so tonight i checked all the spark plugs leads etc for all 6 sparks.The car is getting spark and in the correct firing order.

I also tried to get fuel to it by running a live feed to the fuel pump but this still did not allow it to start.

Im guessing the injectors are not opening to allow fuel to be sprayed and then lit by the spark.

Any thoughts?

Also just to clarify....My 92 vr6 ecu and loom do not have an immobiliser do they?

[VR6 Conversion]

Good point.Last weekend when the engine was going in me n my mate who did the conversion checked this.We took the inlet manifold off and put a piece of paper in to see if the injectors were spraying and they were.

However when you had the problem would it allow it to spray then cut it off?As this may explain.we only checked if they were spraying on start up but coodnt check if they continually sprayed.

How did you manage to resolve the problem?

[VR6 Conversion]

Ok so i changed all the relays and yeh i see what you say it would have needed to be different.The relays were different,so they are all in now.

Sadly still woodnt start.

Though i decided to make sure it was getting spark etc again.So i checked from coil to dizzy and yeh its getting to there.Checked from dizzy to spark plugs and it seems to be getting there too.Its not a large spark but still sparking.

Went around all the plugs and leads and tried to start it up.It tried more this time and i was getting the engine now to seem as if it was turning over.

Every few attempts it would seem as if it was going to start but then it tries and then dies.This may seem strange but i tried not having the leads and plugs into the block as tight as i dont have a vr6 lead puller/pusher and the looser they were it seemed to want to try and turn over.Meaning the lead was very tight onto the plug but the plug was loosely in the block.

Anyone any ideas?

[VR6 Conversion]

Clarifying things bit by bit here.Good to have folk to bounce ideas and thoughts off as me and the mechainic doing it are out of ideas.

Well that numpty question isnt so bad really as.....i havent changed the relays over i left the gti one....i shall go and try that just now.

I see what you mean about the cobra..if its not into the loom i put in for the engine and ecu it cant be cutting into it to stop anything i guess.

[VR6 Conversion]

Thats what i needed to know.Weither the immobiliser would be active or not.So really i can just take it right out yes? The part round the barrel and the vw immobiliser box behind dash?

Yeh the colour concept has a cobra alarm built into it which is aftermarket.Could this be the problem if it may have been connected to the vw immobiliser or atleast passed through it?

All the replacement parts were bought brand spanking new from euro car parts.

Yeh i saw the engine running i even drove it.It was my mates which the chassis was bent and so i took the engine etc and scrapping the shell.

[VR6 Conversion]

Im not sure how vag com will go down with the whole fact its stil got a obd2 plug in port but for an obd1 ecu engine

Get what i mean?

[VR6 Conversion]

Hey,

So doing vr6 conversion into my 97 colour concept.All going well,the engine,wiring loom,shafts ecu etc are all in and its wired up.

Come across a problem though.

It wont start!

Iv been checking everything and have came up with a few ideas to what it could be but looking for some more views.Iv checked all the normal things like making sure its getting petrol,spark etc.

Its geting power to the coil and then passing it to the distibutor but its not going anywhere from there??The rotor arm spins but its not passing to the cap to then go through the leads to the plugs.

I have changed the leads,plugs,rotor arm,distibutor and also tried changing the coil.

When i go to start it you can here the starter motor turning trying to start.

I thought the gti immobiliser may be playing a part in it.The vr6 i took the engine from was 92 obd1 and didnt have an immobiliser like the gti.

I have just spent the last few hours going through all the wires in the fuse box with a wiring diagram but cant see any problems with all the Block connectors into the box.There are however a few wires,single pin ones not connected but theres nowhere in the box for them :s

Looking to see if anyone has any ideas?

[VR6 Clutch Cable 02A Box]

I would have changed the hydro clutch over and that as iv got the vr donor car just sitting there but i couldnt be bothered with the hastle and i dont mind having a heavy cable clutch.Been used to it from all the golfs iv had so didnt see the point in changing.

Cheers for saying though mate

[VR6 Clutch Cable 02A Box]

Hey,

so im getting on with the VR6 conversion into my mark 3 colour concept and i had bought a cable clutch conversion kit to save me changing over the pedal box to make it hydraulic.

Anyways to day the new clutch cable snapped which came with it but im not sure which cable to buy to replace it.

Its an 02A box vr6 standard but is now running cable clutch mechanism.Does anyone know what cable i should be buying?

The one that came with the kit was off a mrk 1 or 2 i think but i had to modify it to fit.Happy to do this again if needed but thought there might be a correct cable out there for the mrk 3 to save me modifying the cable connectors to pedal etc.

Any help appreciated

[my vr6 with its wheels back on, lots of pics ,,phhhaaat]

Absolutly amazing.Love the bumpers on it are they mark 4 ones made to fit?

Beautiful

[OBD1 Vr6 conversion]

Selling the gti and buying a vr6 isnt really an option as iv already got the vr sitting in my drive all stripped ready for the engine to be lifted out.

When you say only change the loom to the fuse box i take it you kept the obd2 dash loom on place then.If you have any other things which you think may be worthwhile me knowing would be greatly appreciated as ready to get on with the conversion.Just trying to sort it all first before taking the gti off the road for a bit to do it.

[OBD1 Vr6 conversion]

Hey,

Im doing a obd1 vr6 conversion into my 97 2.0 8v gti and am looking for some guidance with the issue of changing the obd2 of my car to obd1 of the vr6 engine.

I have the full vr6 car which im stripping and using.I have the engine gearbox ecu wiring etc which is all needed but will i need a conversion harness to save me from change the whole cars wiring loom inside etc?If so could you point me in the right direction

Any other help appreciated
