Need help 98 xj overheating
Ok guys, need your help. My 98 xj has been having an overheating issue for a few days and did not have heat. Yesterday the thermostat, gooseneck, and sending unit on gooseneck was replaced. The heat was working- but now when the heat is on it's overheating again. This morning was driving it, turned heat on and it started overheating and sputtering then it backfired and died and now won't start.. What could be the problem? The fuel pump is turning on and it's turning over but just won't start. Any ideas??
