1998 Chevy Vortec 350 getting fire to the Coil but not from it to distributor?

bad plugs, bad wires, bad coil, oil on plugs, water on plugs

There is no coil in a distributor . That will be the ignition module . The coil will be external and can be found by following the centre ht lead from the distributor back. remove the distributor cap and rotor button --undo any small screws that hold the module in and lift out.

You could have got a motor from a non running vehicle. Did you use the distributor and coil from the donor vehicle, or did you transfer your distributor and coil to the used engine you bought? Check to make sure you have power going to the distributor and coil first. If you have fuel getting to the cylinders, and ignition voltage, going to the coil, you might have a problem with the distributor system. Those engines are notorious for this problem More often or not, the ignition module failed. The pickup coil in the distributor has a high failure rate too.
