Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When I first bought truck I replaced a fuel pump and a thermostat it had a small leak in radiator. my dad said it was a seal or something and after drivin it for bout a month and half and keepin check on the leak he said it sealed its self up lol but it wasn't leakin or running hot. Now like a week ago I go to crank it after just gettin gas and it won't crank I gave it a min and then it started but it smells bad and is making really bad sounds under hood I replaced all freeze plugs and thermostat and patched leak in radiator like guy said but now it is cutting off while driving smokin bad making more weird sounds but all my Gage's are reading good all my fluids are good what could this be

No way we can help, it's going to need a mechanic and some hands-on testing to know for sure what the problem is!
