I'm buying it from a friend it sat up for a while and after I changed the throttle body, plugs, all vacuum lines and injectors and it started rite up and I killed it after about 5 min and checked the oil an all seemed good but truck would not start back up smelled like it is flooding out I then changed the computer today but didn't try to start bcs had gas in oil again( I ran out of daylight to Chang oil again). When I checked the oil after it ran it did not have gas in oil how can I fix this? I work at a junk yard so I can get parts off of other trucks but I don't know what to change
