I'm going to guess TIMING BELT. Fairly common with this engine. Thankfully, they are a "NON-interference" motor so it didn't do any damage when the belt snapped. Just need to replace it. Should cost around $300-$400 depending on where you are. Good luck!

Any auto parts store will have those fasteners.Most just push in(one time use only)and others are two piece and can be used over and over.You will need to know the size of the hole where the fasteners lock into.

take the inner fender well out, unbolt the fender from the bumper, take the 2 bolts out under the car at the fender, lastly take all the bolts along the fender out, and gently pry it loose

Factory timing for all 90-93 normally aspirated Celicas (ST, GT, and GT-S) is 10º before top dead center (BTDC). This means when the crankshaft angle of the number one cylinder reaches 10º, the spark plug will fire. It fires before it reaches top dead center (TDC) because the flame front takes time to fully combust and push the piston downward. this site might help u .http://www.toyotacelicaonline.com/timing.htm

sit on hood or pound on it (center front) while assistant pulls cable release from inside..then adjust stops so it wont happen again...have you had a fender bender recently?

I have done this for years and am familiar with these cars. The first thing to do is cut in your parts, by that I mean paint the inside edges of your door, fender and hood before you install them. The hood is a no brainer. four bolts probably ten millimeter. The fender is not very hard either, remove headlight and side marker and front bumper. The door needs to be disconnected under the dash and the wires pulled out before removal. Install the door and adjust it till it fits and closes properly, then the fender by lining up the body line before tightning into place. Before putting in the bolts along the top install your hood and align it with the back of the cowl so that it is even gap all the way across then adjust fender gap and tighten down. This will work perfect if your inner structure has not been bent or knocked over. Be glad to help further if you need it

Only 87 -89 convertible fenders will work on the convertibles.
