id stripped down my inner roof to clear my drainage tubes and afterwards myy car wouldnt start. my immobilizer is ruled out as i got the car into the reds but nothin happened when i turned the key. no clicking, just nothing at all. i bumped the car down the hill, got it goin then noticed this vacuum like noise. sounds like the fan to me but the fan wasnt on. heres a video of it.
