Technical Help needed starting 95 B

[Lluis Elson]

http://download.fiatforum.bg/Books/Barchetta/ - maybe there is something useful.

There is also a "method" for all Fiats: use manuals (and parts) for other models from same era, with same engine (and ECU family).

I try with another B ECU from the same year and i can't connect

But there is nothing wrong with the key, no need to look for another key. The ECU is not communicating, that's why IMMO light stays on. If it was the key, you could have connect to ECU and it would even throw an error related to problem reading key code.

That's right. Main problem is i can't connect to the damm ECU

Check the fuses. ECU line must have a fuse, see if that's ok. Check if you have 12 V on the ECU's power pin.

Hi! fuses checked and are ok. We'll check the 12v ECUs power pin next week. Thanks

Hello everyone. Yesterday we were checking and we saw that the ECU connector only has two wires. As far as I know, these connectors should have 3 wires, right? Forgive my ignorance. I'll try to upload a photo when I can so you can see it.
