Hey guys I have an 03 4.2 trailblazer. I was going down the road tonight and all of a sudden I lost power and the low oil pressure warning came on. I pulled over and tried to start it and it would crank but then go right back dead. I checked the oil and its full. When it would crank it would go up to about 30 pounds and then the truck was missing and running terrible and would die. Anyone have any suggestions? Thanks.
