No need to if the distributor was not moved.
Try replacing the distributor cap.
you need to reset the timing the distributor did not go back in correctly
restabbing distributor and setting time I'm replacing 4 cylinder motor in a 87 Chevy s10 how do I install distributor and get the truck in time
no spark to plugs
Try replacing the distributor
Assuming you mean distributor cap and rotor, yes, if you mixed up the firing order.
I'm not a mechanic / technician but ( no ) If you are only replacing the distributor cap , it only fits on ( 2 ways ) The correct position and 180 * out
Researching this for my sister in law. Seems most people have found it to be the optical sensor in the distributor or the distributor itself. Sensor cost almost as much as the distributor so makes sense to change both by replacing the distributor.
try replacing your distributor, distributor cap, rotor, and maybe the spark plug wires.
I would suggest replacing it if someome stole it - otherwise if your car is young -look for causes of poor spark operations in the plug wires and related spark supply components. Usually, a distributor needs to be replaced when it is worn or malfunctioning and repair or rebuild of the distributor in no longer possible, or would cost more than replacing it.
the O ring on the dist housing needs replacing
