I was changing the plugs and must have loosened up a line on top of the engine that distributes out fuel, one day later after driving the car around for the day I parked and the came back to go down to the store. When I tried to startup I noticed that she wouldn't and I smelled gas coming for the engine when I got out of the truck I noticed gas pouring out on the ground form the engine. then I observed the engine to see that there was a connection line that had came off from the top of the engine where I had been working putting in the new plugs I replaced the line and observed the oil stick only to see that it was full of gas. So I drained the oil and changed the filter and cleaned the plugs then I let it sit for a day draining and the next day I put in fresh oil after that she turned over and started up but would not stay running only stalling out after several attempts I noticed that gas had gotten to the fresh oil and the engine had locked up again. Please can someone please tell me what could be the problem?????????
