I have a 2009 V8 Vantage, which I'm having starting problems with.
It starts well when cold but turns over more than I'd like once warm.
Its been plugged in for checks, and had an injector replaced.
Has anyone else had a similar problem and managed to rectify.
Thanks.

 

Get under the car, remove the back section of the RH front inner fender liner, and look for a stud that has two power terminals on it. The nut might've backed off.

That was what happened to my '09 Vantage that started with the same symptom. This is where the power cable from the battery connects to the power cable to the starter.
