Technical Security Failure

[midway]

Anyone ever had this problem? My car just wont start!!!

Everytime I try and start my Fiat Stilo 1.6 an error message occurs and nothing happens!!!

the error message is " Security failure - Lost Connection"


Its really starting to annoy me......I've replace the ECU and still nothing!!

thanks

Tell us what checks you've done.
Checked out the aerial pick up ring around the ignition switch for bad contact?
Replacing the ECU can bring its own security failure problems

Did you replace the ECU with a used one?
In that case it'll never work because it's not paired with the bodycomputer.
