A friend has a 92 3.1 camaro and were having some issus Well it runs cold but falls on its face around 4500-5000rpms... if vehicle gets hot it will crank and no start. have fuel no injector pulse w noid light. (pcm was replaced at chevy dealer a few months ago) I checked wiring diagram and when i put my test light to power and probe any one of the injector wires it lights both blue and pink w blk chaser on pass side and both green and pink w chaser on pass side. so i believe that something is shorted to ground. if i unplug all 6 and probe the harness to the rail i have injector pulse while cranking. i removed the injector harness from car and couldnt see any real issue smacking me in the face. So my ? is has anyone ever ran into this with these 3.1's and can steer me in the right direction.
