I had the car towed to a local garage, who had the car for a week and did numerous diagnostic tests. I was told the ECU was garbage and that having got to this point with an alfa, the costs associated with having all the relevant parts replaced and recoded it was better to scrap it in.
Luckily I popped over to a local indi, Simply Alfa and spoke to Colin who gave me the heads up about the fuses as you had suggested.
So with the spare key in hand I went back to the car and tested the fuses and boom!!! the main fuse had blown.
With fingers crossed I popped back over to Simply Alfa the next morning to bother Colin again before he had even had chance for his first brew.
Luckily Colin pulled a replacement fuse off one of his breakers.
I replaced the fuse and started the car.... she started straight up, no more warnings, no nothing....!!!
What a week.....!!!
So again a BIG thanks for everyone's suggestions and help.
