Where is cam shaft sensor located 1993 Chevy 350 5.7?

A 93 does not have a cam sensor. Everthing is in the distributor like the old stuff was.

If the engine has no spark then the ignition module are the pick-up coil in the distributor is bad. I would also check the coil and coil wire. If this don't help you, then ask your question again with your synptoms. GOOD LUCK
