Is the distributor getting power. When cranking you should have 12 volts at the distributor. With the ignition switch in the run position you should have about 6 to 8 volts. Did you have the new PCM programmed to the vehicle using your VIN? Jim

Another thought, is this a security system problem, if equipped? Jim

If you have no spark it is most likely a problem with the distributor. The tach signal is directly tied to the ignition control module in the distributor. It could also be the pick up coil in the distributor.
