So i purchased this 98 k1500 the other day. runs great, but went to start it this morning and it will sputter once like it will start, but it'll just turn over, but wont start. It ran great before that and started when it was warm, just not too sure whats wrong with it. I was told the fuel pump was replaced. (The fuel pump does turn on when i turn the key) and the truck doesn't have cats or muffler, just a y pipe.
