1995 factory manual, PCM power is thru the ECM Batt fuse 9.
The ECM IGN 10 fuse supplies the injectors, PCM, and ignition module. A shorted ignition module transistor would do that. Disconnect the power to the distributor and try again.
If not, disconnect the injectors.
After a 2 second fuel pump prime, there wont be fuel pressure without ignition pulses, that prevents fuel flooding and fires
