Technical Do I need to get my ECU reprogrammed/repaired?

[koalar]

Not this one is it? Was tucked into the fusebox.

Might well be it’s got the right number of pins

Have to find what colours are what my colours are listed in Italian

Back in a minute

 

[koalar]

Can’t find the wiring quickly from the right side and convert from Italian to uk. We are loosing the light


One of the larger corner cables should measure a dead short to the injectors and have battery volts on it

Okay - I popped the the battery out to look for this plug so let me pop everything back on.

When you say injectors do you mean the ignition plugs that showed low voltage earlier?

Do the injectors

Each one has two wires

One cable is the same colour on all the injectors this should have battery voltage

F22 20A is worth checking

 

[koalar]

Injector and coils share the same relay, fuse and wiring

Both should have battery voltage with the ignition on

 

[WildFeraligatr]

F22 fuse is OK.

I've pulled out 2 injectors, both have a red/brown wire which is showing 0 volts on both. The other wire on both shows around 1.9 volts when testing at both the battery negative terminal AND when testing at 3 of the 4 corners (point L is the one without voltage per your diagram).

Post here so bothersome to keep looking them up

A Light Blue
B White
C Orange
G Yellow
H Grey
L Blue
M Brown
N Black
R Red
S Pink
V Green
Z Violet


The cable you want is MB brown and black

 

[WildFeraligatr]

I'm gonna have to go inside now as I'm starting to be unable to feel my fingers but keen to hear your thoughts.

Missing 12volt here

 

[koalar]

Told you the wrong fuse sorry

F17 10A

 

[WildFeraligatr]

Sorry when you say missing 12volt, do you mean a component is missing or do i just need to check the fuse?

I'll give the fuse a check but i would be surprised if it's missing something else if it was running ok before?

 

[koalar]

This one is the correct brown and black

Should be battery voltage with the ignition on

Are you sure both half’s are in fact connected. It’s possible to have been accidentally disconnect while removing the engine

I can’t see the others half tab in the photo

 

[WildFeraligatr]

Right - as stated before I have voltage at that wire, but also at 2 of the other corners (the one directly above where you've highlighted doesn't have voltage).

Do you mean are both halves of that plug connected? If so, then they are very much connected as I did try pulling it apart and it was having absolutely none of it.

12V isn’t present at the injectors

Something not right relay, fuse, wiring are the most likely

I suspect the connector D004 it’s selft in the fuse box in my car but underneath

May have got tucked out of the way during the removal of the engine

 

[koalar]

So you battery voltage on the brown and black wire ignition on

Yes/no

 

[WildFeraligatr]

So you battery voltage on the brown and black wire ignition on

Yes/no

No - 1.95V, same as at the injectors.

 

[koalar]

No - 1.95V, same as at the injectors.

Great

Until we get battery voltage here nothing is going to work

The connector is a joint. I am hopping it’s the other part hasn’t been pushed together properly

The other part? What would i be looking for there to see if it's been connected properly?

 

[WildFeraligatr]

Just been looking at the wiring diagram again to try and understand it - would fuse T09 want checking as well?

 

[koalar]

Next move would be to separate

This

And see if the corresponding pin the other side is getting 12V

There isn’t enough visible to see if bottom half of the connector is even plugged in
