My plow truck is a 4.3 1991 Blazer, it was working great but after 20 minutes or so it began to smoke, then stalled out and now it will crank but will not start. The oil, transmission (auto) fluid, and gas are all ok. I hope someone can help me out

  • Welcome to the site. You have not given very much detail to go on. Use the edit feature to add things like; if the Check Engine light on. Do you know what the source of the smoke was? Was it under the hood, under the vehicle, from the exhaust, etc? Is there spark? Fuel getting to the engine? – CharlieRB Mar 26 '18 at 15:55
  • Does it have any coolant? – MooseLucifer Mar 26 '18 at 15:58
  • it does have coolant, there is no check engine light on, I believe the smoke came from under the hood but alot of it came into the cabin (inside the truck) it seemed to have a burnt plastic smell to it. So now its cranking but not starting – user36401 Mar 26 '18 at 16:10
