91 toyota celica gts where do the two alternator connector wires opposite...

Check dimmer switch located on steering column

last time i heard of something like that someone stole the driveshaft. in any case you'll have to get a look underneath,

There may be several reasons for this. 1st, low transmission fluid levels can cause the gears to grind while shifting due to lack of lubrication. I would suggest checking the fluid level, there is a plug located on the side, in about the middle of the transmission which when removed should slowly seep oil from it. If it doesn't then you will need to add the recommended transmission fluid.
2nd, a maladjusted clutch can cause the same problem. Even though you have the clutch pedal to the floor, the clutch pressure plate may not be completely disengaging from the flywheel. This will cause pressure on the gears and synchronizers while trying to shift. I suggest having the clutch adjusted by a mechanic if you have never performed this function yourself. An inproper adjustment can severely shorten the life of the clutch.
The 3rd option may be a warn clutch component like the slave cylinder if equipped, the throwout bearing or even the pressure plate itself.
A visual inspection can be made of the clutch by removing the inspection plate from the bottom of the bell housing to view the flywheel and clutch. With someone depressing the clutch you should be able to see the clutch moving off the flywheel.

There are 2 possible areas. 1 is the fuse box beside your left foot. 2 would be in the engine compatment on the right.

just ram the shifter in your booty,.....duh

starter drive might be bad... fly wheel bad spots poss bad starter you sure its not just clicking???

You probably have a broken retainer pin on the VVT (Variable Valve TIming) controller, which is located inside the cam area on the cylinder head. Not something that I would fool with if you have no experience removing the cams. Best left to a professional. Unfortunatly, quite a common problem, I have done 6 this year.
