only way to get raw fuel out exhaust is stuck open injector or two....
You can identify the negative signal coming from the PCM to each injector...the red wire gets powered with key on, the other wire is a pulse signal from the PCM....each injector should click click clickÂ
If no click then chances are you have a dead short somewhere in the wiring or in the PCM
Do you have a noid light? a multimeter?
FYI I have seen more then one 91-94 PCM have internal issues lately, they are getting older..........
