CTI Kjet problems - what are my options?

Post by Soljah1 »

So today i had a bit of a cry, the fuel dizzy finally packed up. no fuel is being fed to the injectors.

So what i need to know now is what are my options?
was going to do a MP9 conversion in March next year but was thinking of just doing something that is cost effective now like just a management(diktator), mp9 fuel rail and injectors. not sure what else i will need. what would the cost be?

what can i do now to get the thing working again? or is it totally gone?

Low fuel pressure from the pump can also cause that, just confirm that your pump is 100%. More people are going EFI so it shouldn't be a problem to source a working fuel distributor for cheap.

Bud we just completed our latest golf 2 GTI from K-jetronic to a 2litre 2E motor. We actually map an MP9 ECU to work on the motor. If you need any help just send me a PM. My company is called Stwiggy's Service Centre.

What is the correct reading? 2bar?

K-Jet should be around 5 Bar if I remember correctly. Panic might confirm.

I havnt tested the fuel pressure yet. What I managed to do is get a new petrol pump and checked if any petrol was getting sent out of the fuel dizzy. I just removed the injector line from the dizzy to see if any petrol was getting pushed out. But nothing come out, on all 4.
I can only get a proper fuel pressure tester tomorrow or tuesday.
I even held the airflap open while my buddy swung the motor but it just sputered and died again.(this is without anything removed from the fuel dizzy.)

At the first sign of trouble you wana throw in the towel ,convert to this and that , WHY?

Im by no means a mechanic but have had most symptoms Kjet can throw at any one person.
Everyone knows a well tuned K-jetronic will "KEEP UP" with most modern cars ,

I aint giving up just yet. I actually enjoy the problem solving of it. It does become frustrating a times tho.

I was saving for a turbo upgrade so just though I might aswell change to managmet if it does come to that. Im not even going to change the head.
Plus i know the power of the Kjet.

I have the hynes manual and it helped alot with other smaller problems. Which is why i am now turning to the forum for help now.

Did that also.
Even made 100% sure the ignition system is working. Got new plugs leads and gave the distributor a good cleaning......

Nothing happend.

Check that there is fuel pressure at feed into dist then also check on the banjo bolts there was a very small filter.there was a tpi years ago to remove it as it blocked.then also just check the regulator on the side of the fuel dist that it also has no dirt in it.also check that the pin that the plate moves is free.

I no speak the Lingo.

The fuel pressure is fine. Measured 5bar into all the way into the distribution block.

Ai! Look like i wasnt the only one having Kjet stress. :bang:

I was on the verge of giving up as well, I went as far as buying a brand new Diktator from Ferolli, sourced a 5cap 1.8 mp9 head and had it redone and port/polish and got an intake and throttle body. But before being too hasty, I read up a bit and Googled some shizz and used the search option on this forum (which works quite well these days). :fear:

When i got my car it had a very unstable idle, spluttering, pinging was sounding like fire crackers, very very thirsty on juice. Used to get 300kms on a full tank. Dizzy had to be turned down so far that the car felt dead and unresponsive, would idle very low to prevent pinging. And YET it still pinged.

All i did was buy new o-rings for the injectors, checked injectors while they were out and the spray pattern was still surprisingly very good. Although it does drool/drip on idle which gives off bad fumes. Tightened all screws/washers on any pipes to prevent air leaks, radiator flush and topped up coolant, cleaned and lubricated the plunger in the air box, replaced the inline filter that sits close to the pump infront of the rear wheel. Threw in a bottle of injector cleaner. And problem solved.

Advance the timing on dizzy after everything was done, turned the air screw on the throttle. And now the old girl is running like a steam train. No pinging (even in the CT summer heat), very responsive and oh so light on petrol. Tank is currently sitting dead centre and covered 260km's so far. :troll:

The banjo bolt are the bolts that hold the pipes onto the fuel dizzy.The main feed into the unit has a micro filter in it check that filter.
