I bought the truck new in 99, it has about 250k on it. I did replace the relay switch,but that didnt seem to do any good. If I plug the truck in all night it will start no problem. Its a stock truck the only other problems I ever had is that I have to replace the alternater about once everey...
I have a 99 f-250, 7.3l In the mornings when its chilly (20-30 above zero) my truck has a hard time starting when it does it blows alot of white smoke out and runs rough for about 5 minutes, then everything is normal. When I get off work It seems to start easier, but it still blows alot of smoke...
