What would cause no spark in 1991 Chevy Camaro RS V6 after replacing spark plugs spark plug wires distributor cap and rotor Motor turns over just no spark?

Answer 1

Heh... sounds like another victim of the VATS antitheft system. Try to crank it and look at your instrument panel. See if the security light comes on. That would be the antitheft system. Those cars are pretty bad for the connections in the ignition cylinder wearing out after a lot of use. Basically the resistor value in the key (you can't miss the chip) has to match up with the value required by the system to start the car. Sometimes the contacts in the ignition cylinder become worn out and an incorrect reading of the resistance is sent. Incorrect resistance = no crank. Also, one of the wires that connect to the ignition cylinder could be broken off and you wouldn't know it. Check them out. Some people measure the resistance of the chip in their key and buy a resistor from radio shack and wire it in on the circuit side of the connector.

check the engine coil first its only a 20 dollar part if still no spark 9 out of ten times its the distributor ive replaced mine twice make sure u have the engine at TDC and not the compression stroke before removing the distributor

You may also want to check the ignition control module. It is located under the distributor cap and the base of the distributor. There are two plugs to disconnect and two small screws that hold it to the base. It is a cheap part, and much cheaper than tearing through the VATS stuff. Replace the module and pray like heck it works.
