same thing happened to me recently. Be sur to first check for spark and fuel. Unplug and replug the ecu under the passenger foot well.
or replace the dme relay. If you dont have one. jump relays by getting power from 85 (I think) and running it to the 2 30's (I think) where the dme sits. you can power the fuel and ecu that way, unless something is wrong. Good luck

check the screw on the rotor

Same syptoms, but turned out the DME computer was the culprit. I ended up rebuilding it myself. Search for some of my posts on the subject.

Before you jump to any conclusions, you should run the step-by-step test procedure described in the factory service manual.
