My 92 Corolla died on the freeway. It acted like it ran out of gas. The fuel filter was clogged, changed it. Then it started, ran rough. Then it wouldn't start again. Changed fuel pump. Still won't start. What should I check next?

Check to see if your timing belt broke. Remove the Distributor cap and watch the rotor as the engine cranks. If the rotor spins then the Timing belt is at least in place. If it doesn't spin then the Timing chain/belt has broken and will need to be replaced. You will also have to have the valves checked to verify they have not bent after making contact with the piston heads.
