I have an '02 Sierra 177,000km on it. Had some sputtering and shaking starting the truck the last few days, not sure what it was. Possibly the Canadian cold, same results starting the truck this morning. However when driving, I had full loss of power (not electrical at all) to my truck. Tried restarting after pulling over and the truck turns over but does not start, or if it does it's dead again instantly. Spark plugs? fuel pump? maybe the ignition somehow. Curious what's going on with my truck. Any help would be great. Thanks GM folks
