Question about 1991 Ford F150
Well i really would investgate the burn marks more but if it only starts dead cold then i would be thinking what changes when it gets warm and stops it from starting and running after warm. seeing you replaced all of that stuff doesn't rule them out and a dist. maybe not the issue but a module may. it also may have something to do with the temp sensor. it could be broke and telling the eec unit to rich the fuel up like a choke and not leaning it out when it gets warm because the sensor is still telling it is cold. just a few quick thoughts.
let me know any more info that could help.
