First, did you check the wiring to the distributor? Make sure it's getting the correct voltage (don't forget to do the "wiggle" test). There could be a break in the wire/connector. And you didn't mention if they replaced the ignition module?

Also you're computer needs to see a signal from both the CKP and CMP before it'll tell the ignition to fire. But this will usually set of the check engine light if there's a problem with one of these sensors.
