Six Cylinders Motoring Notes

[Six-cylinder]

id cry if beemer got it (and im no fan of beemers)

 

you have pic of 77 spec herald

 

have you pic of 77 spec chris?

In production until 1978.

[richardmorris]

Wow. I've not seen one of those before.

[Six-cylinder]

Wow. I've not seen one of those before.

We think there is only one in the UK.

 

Developed from the Herald in India.

[DSdriver]

Can you get a front door off the car that the rear door came from? Then you can add some Smart badges

[dollywobbler]

At least you haven't got to worry about a paint match...

[purplebargeken]

Bloody hell Chris. I can't keep up with the variety and number of cars you have lol.

BX GTI 8v tinkering today, we have drained the old fuel and it runs on easy start but not on petrol. There is petrol at the fuel rail union and the plugs were dry so I guess either the control unit is not telling the injectors to fire or they are gummed up by 8 year old fuel. How can I check?

 

What type of injection do I have?

[hairnet]

if there a hbol or a gary cox about itll tell you i think

[DSdriver]

Would a good dose of Carb cleaner work?

Not sure, I would like to test if a signal is being sent to the injectors but don't know how?

[Dave_Q]

I've previously used something like this to test injector wiring.

You plug it into the injector connector and crank the car and the light flashes away if the electrickery is getting to the right place.

 

Please note I don't know if that actual set contains one that will work with your BX, probably though as nearly all cars use components from one of about 3 mobs eg Bosch.

[Cleon-Fonte]

According to the HBOL Bosch LE3 Jetronic was fitted to BX GTis until July 1990, and Magneti Marelli Motronic MP3.1 thereafter.

[Mr_Bo11ox]

Those noid lights are dead handy, I've got one somewhere, would never have got to the bottom of my Argenta's injection problems without it.

[Sloth in a bowl]

Maybe idiot question, but you have checked that the fuel pump(s) are providing pressure to the injectors?

[Ian_Fearn]

Have I missed if its sparking or not? Its been about 10 years since I owned GTi BXs but I seem to recall it won't inject fuel if it doesn't detect spark first.

 

In my experience of the 8v BX GTi, the problem was nearly always the ignition module (admittedly running on 2 cylinders was the normal problem). Its a 7 pin unit if I remember rightly for the later system. The earlier version was 6 pin.

Judging from the underbonnet picture earlier in the thread, it looks like Bosch Motronic 1.3 management to me - I assume this is a CAT equipped car and has a lambda? Rare beast in the UK if so, as most were non-CAT.

 

Non-CAT cars are as in the quote above (although it's Bosch rather than Magneti Marelli) but yours clearly isn't MP3.1 due to the AFM in the picture, plus the inlet manifold is different on the non-CAT XU9J2 engine.

 

Given that it'll run on easy start, you've presumably got spark and thus the crank sensor, ECU etc are working as spark is controlled by the same ECU as the injection.

 

Sticky or gummed up injectors are possible, I've seen it before on XU engines that have sat for a prolonged period. A sharp tap with a spanner whilst cranking over will often free them off, otherwise those injectors are comparatively easily sources as they're used on various XU9 engines, some Volvos and a few other cars. I should have a set somewhere if needs be.

 

One thing that's worth checking is the wiring. I've not seen the loom for a late 8v BX GTi, but the wiring on BX 16v's is a joke, with the injection part of the loom connected to the main engine management loom through an unsealed wiring plug that ends up corroding and giving a bad connection. It's possible that the injector pins on that are grotty, assuming that your loom is built in a similar manner.

 

If you don't have any luck, I'm happy to cast an eye over it when I'm next up Buckingham way and I've got various spares for that engine/management

I have just ordered one.

[Six-cylinder]

I have gussing fuel when I take off the union on the fuel rail and have found one pump under the car.

 

How many fuel pumps does it have?

Yes we have sparks and it will run if you spray easy start into it.

I would love somebody who knows more than me to have a look over it, but the car is still at my mothers house in Princess Risborough.

I can come over and point at the sky if you need, but that will be as far as my knowledge goes...

Thanks.

 

My friend who sold the car to my Dad in 1993 has been coming over with me and has a basic knowledge, but now I need technical help!

[Bear]

Can you pull the injectors and give them a clean and new seals? Took 10 minutes on the Volvo, but it doesn't have a fuel rail to deal with - still quick though. You can crank with the injector aiming into a jar to see if fuel is being sprayed, too.

I have ordered the Noid test kit so I will check for a signal and them if that is ok I will take the injectors out. (when I say I, my friend will probably help, he did sell the car to my late father in 1993 and it is faulty already!)

I have just checked with my friend who helped me put fresh fuel in it and it is an unleaded only fuel filler neck so it must be a Cat car.

[richardmorris]

K reg will be a cat. It was the first year they were required here.

It is a 1992 car and I think that was the year Cats became mandatory.

 

I worked for a Vauxhal dealer at the time and I had to register a couple of Novas without owners because we did not want to retro fit cats.

[Anthony]

I'm sure that we can work something out - give me a good excuse to head over to catch up with some friends in Aylesbury that I've not seen in a while

[Six-cylinder]

So you can jeer and laugh at me come this time next year I am going to confess to all the Project cars that are going to be worked on 2017. The aim is all these cars should be MOTed and useable by the end of 2017, but I am not that fussy about paint work.

 

1984 MG Metro - all welding done engine refitted 2016, now needs wings fitted and MOT stuff like Brakes etc. The garage who have it plan to give it back in the spring MOTed so I can use it for the summer, then I will get it painted next winter.

 

1974 Peugeot 504 Cabriolet – it has been painted and is currently in a trim shop in Witney where it has been for nearly 3 years waiting leather repairs, hood and carpets. It was made to run but because the Kugelfischer injection that does not like sitting about probably will need work again and then the usual MOT stuff. I am going to ask that they get it done so I can have it back for easter and then I have exhaust brakes MOT still to do!

 

1983 Citroen LNA Inca – well under way now with working engine, still all the MOT stuff to do, but the car is in the open and the Mech is reluctant to do any more while it is cold and wet.

 

1983 Citroen Visa GT – I have bought sills and a local welder (non car) has agreed to do the welding work for me

 

1985 Range Rover 3.5 4 door – The garage that originally took this on closed down and it was sent to another garage who did very little. Then another garage started the work and stopped. Currently it is waiting for somebody to take it on, I don’t really know what is needed and have not seen it for years. I will push in the spring for it back but it is no good to me without an MOT.

 

1983 Alfa Giulietta 2.0 saloon – It should be under way by now, starting with my friend sorting the bodywork for me in my home garage but a couple of rust spots on the Bi-turbo have turned into a marathon.

 

1968 Triumph Spitfire Mk3 fitted with 2.5 LTR engine – We got it running in September at the Field of dreams open day, I took the fuel tank out because it was full of crud and now the tank sits in my garage. Still needs all MOT stuff. Again it is sat in the open and is unattractive to work on.

 

1971 BMW 3.0S saloon – poor starting, poor running and sticky brakes, a friend from the BMW club has had this for the last year or so and says he will return it sorted in the spring!

 

 

Then there is the smaller stuff like the Heater matrix has gone in my 1995 Audi Convertible, 1999 Volvo V70 T5 immobilizer fault, 2nd 1990 Volvo 740GLE non starter in Wales, 1976 Sovereign stripped adaptor for oil sender, 1973 Sovereign showing high engine temp, etc

 

And the usual round of MOTs, 27 currently MOTed cars to keep on the road.

 

Looks like it is going to be a busy Car year for me 2017!

Not a single one is on the road yet!
