I rear-ended someone and it didn't do much damage, hood and grille are totaled, and the radiator is a bit smushed, but nothing is leaking. After the collison it wouldn't start and i'm trying to figure out if there is a fuel pump impact sensor and if there is a switch somewhere. Where should I start the diagnosis.. I tried the connector under the seat with a wire to read codes, but it doesn't seem to work. Everything looks fine for it to start. Help Me!!! thanks in advance Peter
