i had to take it out to replace my fuel pump a while back.. and when i put the seat back in on the passenger side in the back, it wont go all the way down.. it acts like its clipped together with soemthign caus ei cant pull it all the way out, but the seat just kinda sits there about 3 inches (unless some1 is sittin on it) from where it should be snug with the floor... any help here?
