Well aside from yor car getting hit, (mine was rear ended tuesday) your supposed to drizzle the sea foam into the intake while the car is running. Once the seafoam is gone, you kill the car for 5 mins. Then fire it back up. Prepare for the fumes and take it for a drive right away (not you) to blow the shit out, otherwise your going to piss off your neighbors. If it won't start right now, what you need to do is spray from starting fluid in the intake, that should fire it up and then it'll be running and should start pushing the seafoam through the system.
