Is the injector actually jetting fuel into the throttle body? Ifnot the injector could be fouled. Make sure you have spark from the plugs. If not check the coil\distributor. if that doesnt work, make sure the vehicle is not backfiring because that is caused by a bad timing.. check your injector a+b fuse, and check the wiring running to the injectors...

Toyota Camry throttle does not return after depressing was told the throttle body needs replaced Could it be gummed up or a bad return spring Garage wants 1000 to fix?
I believe Toyota went to a an electronic/electric throttle design in 2002. There is no mechanical connection. A spring on the accelerator pedal returns it to the start position. There are products available at the parts stores for freeing up the throttle body. If you have a car with a mechanical hook up to the throttle body you can free the cable up with products available.
How do you tell if your car needs the fuel injector replaced?
I had a 1987 Pontiac Grand Am I found out that the injector needed to be replaced when the car would start for only a few seconds and the die out abruptly. The injector would only spray enough fuel into the throttle body in order to start it then would stop, the injector was located in the middle and above the throttle body making for an easy repair.

What could cause a 93 caprice to turn over but not start you replaced the fuel pump and rebuilt the throttle body?
Did you get some debris in the fuel tank? There is a fuel pump "pickup" filter that prevents debris from enterning the fuel pump. If that filter is plugged the pump will not be able to produce enough filter to start the engine.

Just a thought. If the rotor broke, could it have caught in the cap and turned your distributor and put the engine out of timing? Check the condition of the cap and the contacts inside it,\.
