my 1995, 1500 GMC SLE won't fire up.
So it cranks, but won't start? Check your fuel pressure, and for ignition for spark.
Check Ignition module Napa part TP58
Mine was doing the same thing. I have a 95 sierra z71. I pulled the steering column apart and moved the wires going to the ignition, now it starts. Every now and then it will do it again, so I just reach sown and jiggle the wires going to the ignition. This makes me believe that the ignition is going out or has gone out. I priced tge ignition on lmctruck.com and its not too expensive. I hope this helps with your truck
