I have a 93 ford ranger i recently swapped in a 3.0 and after the swap it fired right up ran for about 20 minutes and i shut it off and buttoned up a few things then i fired it back up and moved it into the driveway and let it run it ran about 10 minutes and shut off and wont start back up its getting no spark but my ground wire from my block to the fire wall is getting burning hot and so is the ground from the negative battery terminal to the body by the headlight any ideas
