i'm surprised Wrinx hasn't the answer to this..he's normally a wizard in 155 probs!
according to the workshop manual you need to test the following if the anti-theft device completely blocks the engine=
with the key in the RUN position,check for 12v at pin B3 of the control unit.
Apparently there are two connectors on the control unit (alarm) which is behind the passenger wheel arch you will have to remove the wheel and plastic liner
You need the connector that looks like this=
****** the *'s represent the pin's
B3 is the top line third from the right
if test is OK restore wiring between B3 of the control unit and Motronic wiring(pin A of G133a)across pin B3 of G241Black
G133a is a three pin connector with a tab on the right hand side when vertical pinA is the lowest pin . G241 is a four pin connector with a tab on the left when vertical,B3 isthe second from bottom
if test not OK replace conrtol unit
Hope this is of some helpI haven't got a scanner hence this drawn out item
I'm by no means a wizard with wires,but from what I can see G133a is the electronic injection-ignition wiring connection which has 3round "holes" and an S shaped tab off the side,which itself has a slot in it.
Pin B is the black wire the lowest when the connector is vertical with the tab on the right.
G241 is the anti-theft device wiring connection. There are 2 of these 4 "hole" connectors, one looks like G133a connector but with an extra aperature(4), you need the other connector with the little square tab on its side. PIN B3 is the second from lowest when vertical with the tab on the left.
according to the wiring diagram they are both in the engine bay on the same side roughly as the control unit N45
Hope this is of help,if you want pictures of these connectors,PM me your Email address and I will Email them to you
I just got into my car to go to watch a football match at Old Trafford, and it wouldn't spark. Spent the entire evening thinking about possible causes, and came up with nothing. The next morning, I just woke up thinking 'I wonder if it's the fuel cut-off?'
Just shows that your brain does sort things out for you while your asleep.
(apparently Paul McCartney wrote 'Yesterday' in his sleep too, it's a bit more impressive than working out your Alfa's sparking problem I suppose)
I think this one may be heading for the nearest afla workshop. I'll give them a shout in the morning and see when they can get it in.
Will post when I get the results back.
It is probably/hopefully something quite simple.
