Hi

I hope someone can help, I have a fiat bravo 1.8hlx.96. I recently had problems with the car not starting( turning over but not igniting) the key code light was staying on. I purchased a virgin ECU and now the car doesn't look for the immobiliser before it starts. I've been using the car fine since, but now the problem comes back every now and then. when it doesn't start I've noticed that the injector light doesn't come on when when I turn the key.

Does anyone have any ideas?
