Ok ia i got a 94 civic that i picked up from a buddy on here and when i went to go test it out it had a dead battery and we got a new one. the car had a bit of trouble starting up but eventually we got it started. we bought the car, drove it home and now it will not start at all. we looked in the gas tank and there was RUST in it..so we get a new tank pump and filter..still nothing anyone have any ideas? btw no check engine lights
