Any ideas? I held the stock in and put the ignition on and it flashed up saying t---. I think it might be a fault with an injector from reading another forum.
You'll need to do a diagnostic scan to retrieve the specific fault code. I've seen this coming up before, done a reset and the code disappeared and didn't come back.
you can always disconnect your battery for a few mins, and see if it resets.... will reset your radio so if you do make sure ya know your radio code....
