Have you ever seen a PCM damaged by ABS or other solenoid in the car. I have a 93 saturn SC2 that blows the 5 volt fuse on PCM B location. Computer won't give any check engine lights assumption is (dead PCM). The ABS brake system is empty due to brake line rust through. I just bought the replacement computer and the instructions say check all solenoids. Do I fix or unplug the ABS before installing the computer? inital problem was will not crank. I have tested the fuel pump it works correctly.

Not a lot of detail. Suggestion is to get repair manual and read up trouble shooting section. Ex. does the fuel pump turn on. if so the issue may be lack of spark. read the code retrevial procedure to get the check engine codes. That is where I would start.
