hmmm the noise sounded like it was coming from the front of the motor.. a real light metal tapping sound. was quite loud. im pretty sure the starter was trying to work but there was no way it was turning over. The car has abit of work done to it, 10psi tune, injectors, fuel pump, cooler, 3.5inch zaust. im guessing I have done the same thing as you. I will be callin elite auto first thing monday to book the car in for them to sus out wat has happened.
