93 camry no spark

I have 93 toyota camry that has no spark.I replaced the distrubtor from the junk yard, it ran for about 50 miles than stopped, no spark. Replaced distrubtor, rotor,cap, spark plugs with new one, no spark. Than I replaced the ignitor, no spark. What should I try next

You might want to check if the coil is defective.


The distrubtor has a new coil in it. Also I have checked all the fuses and relays everything checks out good.

Any stored trouble codes?

That said, possibly the ignition switch?
