ok , i just bought a 94 celica. it's an automatic gt. i drove it a few times and it started with no problem. but the other night when i got to my gf's house and tried to start it again it wouldn't budge. at first i thought it was either the shift lock, ignition, neutral safety switch, fuse, or starter.it so far has been neither. i changed the entire shifter assembly and plugs.nothing. now the car wont let me have my key back unless i remove a terminal from the battery. and when i try to start it the clock goes dim but it wont start. I also ran a jumper from the 12v positive on the battery to the starter and it will crank but not run. and yes i had the key in the on position. does anyone have a clue what might be going on? i also checked the trans. fluid level and its fine.

ok. does anyone know if the neutral safety switch is mounted on the floor shifter or on the tranny. because i'm looking at pics of neutral safety switches and it doesn't look like any component in the shifter mech. that i already changed.
