MK2 GTI filling the intake manifold with petrol

[martinijosh]

That is the Ignition control unit... Just a word of warning... Be careful when you working on the electronics..just make sure the ignition is OFF when disconnecting any of the plugs from the ECU or ICU ( Ignition Control Unit)

You can clean all the terminals on the ECU and it might fix the issue.. Clean the screws attaching it to the body and make sure make sure they are secure

What engine do you have?.. What are the letters in front of your engine number?... This will help determine what type of system you haven and can advise accordingly

It attaches to the body with plastic slots/clips.

I'm a business IT tech by profession so I understand the concept behind keeping things off while you mess with their electrical innards

I'll check the specific engine model tomorrow, I know there are a few types in the 1.8 8v's

Its turning over fine, but not starting. Going to make sure I have spark...

Also, the fuel hose going to the rail has a big clear label saying "Not for use with fuel injection, do not exceed 50psi"

.......



edit: fuel is filling right to the top of cylinder 3, right up to the plug...

Making sure i have spark, and then giving up for the day.

[martinijosh]

Sparking fine on 1 and 2, weaker spark on 3 and poor spark on 4

It tries to start when there is no plug in cylinder 3...


$160 for a set of leads from supercheap. Le'Sigh


looking pretty tired here

So at Camden GTI we have a used and tested ECU for $200 delivered.
It shouldn`t be this hard to make a Mk2 Work.
All HT Leads need to be good, German ones with the shielded end, not the cheapo $20 ones from REPCO that dont work.
New Rotor Button, same as Mk3 $15
ECU should have some sort of earth connector up in raintray where it sits.
Would be good to try another ecu before changing lots of other stuff.
Good luck with it.

Yes I know, I've already been on the phone with you guys about it, the one you have in stock wasn't a digi II

I've sourced an ECU from a forum member, I should have it next week.


The leads and plugs on it now are bosch

[Golf Loon]

Not true, the part number you gave me was not the same, as you said yours is a jap spec ecu.
The one I have came from an Aussie delivered Mk2 and I know it works and give you warranty.
No-one can give you warranty against diagnosis, change the broken part and car works, keep changing expensive bits till car works and that can get expensive.
Good Luck

Re: MK2 GTI filling the intake manifold with petrol

The part number you gave me matched against a digi I and I have a digi II

I also didn't say anything about being "jap spec"????

Thanks for your help and sorry for wasting your time.

Got the replacement ECU from an Aus delivered MK2, ecu codes match "Golf Syncro" which was a 1.8 8v making 72kw, not the 82kw the international made which makes sense with what people saying about the aus delivered golfs were restricted (why....)

So yeah, looks like that may have been part of the problem (wrong ecu). Fingers crossed hey.

[The Fonz]

Good luck...

Here is a question.. i've seen ECU's with different letters at the end of the codes ..for example 037 906 022 M, 037 906 022 DB etc etc.... What do the letters at the end mean?

Thanks

Last letter can be the kicker with most parts, especially if the org doesnt have one, but with some with say an L at the end may take the supercede version of M if that makes sense, but in general its important

Should be fine unless this particular golf happens to be a South African import... not sure why anyone would go through the effort of importing a 4 door 8 valver though?

In this case the letter at the end means the difference between a detuned golf syncro and a regular euro gti 8v

Everything I have read up on suggests that the AU delivered model had a tune similar to the california emissions restricted models.


All very confusing and all very German.

[martinijosh]

It tried to start, got a little vroom out of it then it stopped again. Checked the firing order.... mechanic that first looked at it must have read the 16v firing order as it was set up to be running anti clockwise, 8v is meant to be clockwise.

Fixed that, still no go. Sad kitteh. Going to change the rotor arm, and if that doesn't help it will go to a mechanic who hopefully knows something about these buckets.

Fuel flooding problem has disappeared though, so that's something...

This car has so far cost me $4,200 and I've gotten about 2 months and 1,000km of driving out of it. Deal of the century.

Any luck?
