Anyone work at a dealer? Maybe you've seen this. Got a chevy G3500 Express that has an occasional no start. I installed a new engine(the old one was locked up) and it was fine for about a month. He complained about no start occasionally but if he waited for 5 or so min it would start and run fine. Said he didn't hear fuel pump so we ckd all connections and put new pump in, still did it. Said ignition didn't feel right so we changed switch( electrical switch) STILL DID IT. Finally did it for me, had no injector pulse, ckd ALL grounds, ckd wire harness, connections at pcm, ALL GD! No pulse at pcm, replaced pcm was gd for about 3 starts then back to the same thing no inj pulse! Anyone seen this?????
