OK. this is my problem.
Ive found that on this bravo 1.6 16v the ecu isent pulsin to num 3 injector. So ive pinpointed the fault to the ecu.
OK customer as come in with another ecu off another car, but obviously i havent got the red key for it, i might be able to get my hands on the imobiliser ecu, but not sure. But i have got the red key for the old ecu.
What are my options if any?
cheers lads! and lasses!
P.S> Great forum by the way

you need the main ecu, the immob ecu (aka codebox) and the red key all from the same car. they are permanently paired and all 3 must be together for it to work.

if you have a faulty ecu, to replace it you need all 3 parts from a donor car, 2 out of 3 is pointless.

ecu failure is very rare, have you tested the wiring from ecu to injector? and have you tested the injector? injector failure is VERY common on the 1.6, so common that you expect it to happen.

if you do need to replace the ecu, and you cant get the complete set of 3 matching parts, you're options are a brand new ecu (it will pair with any codebox, but only the first one it communicates with) or a decoded ecu (the immob is disabled when you do this).

alternatively you can hotwire the fuel pump by giving it a new earth, but i didnt tell you that.

Thanks for the response!
I had a look at earthing the fuel pump, but the fuel pump works with the new second hand ecu pluged in, so it iseent imobilized.
It look likes it only imobilizes the spark.
The customer isent intrested in the imobilizer, how can i get the ecu decoded? that looks like the best option for him.
The injector was already replaced, so thats why i've got that ruled out.

weird, i've experimented with immob issues in the past and it has never affected the ignition, just the fuel pump

have you checked for sparks with the old immob?

to get the immob decoded you need to ask tony

It seems to imobilize the injectors and the spark.
I will try that place u told me .
I'll get back to you, and keep you up to date.
