I have 93 toyota Camry it wont fire up after I did the timing belt. It starts before I did the belt. I rolled it in my garage so I know everything works from the ignition to fuel delivery. My timing is perfect, the crank sound perfect but its not firing.
I moved to replace the distributor cap, rotor and coil plus 4 new spark plugs still not firing. SHOULD I JUST REPLACE THE WHOLE DISTRIBUTOR?

Bet you forgot to connect a sensor wire like the cam/crank position sensor or forgot to reinstall a part necessary for sensor operation.

Car not equipped with cam or crank positioning sensor...

I meant those as just examples of sensors. Check any wiring to sensors that was disturbed during the timing belt job. The problem is most likely electical and not the distributor. It is hard to understand how a distributor could go bad at that time.

is the engine(4 cyl.)a single or dual over head cam??
have you run a compression test??
have you double checked the timing marks??
