Ford Repair: 1990 mustang gt, type of plugs, mustang gt

Question
hi, i have a 1990 mustang gt 5.0. it starts fine when its warm out, but if its cold at all it will not start. the only way i can get it to start in the cold is if i stick a heater under it. it has spark, fuel,etc   i dont know what could be wrong. its really bugging me.

Answer
hey there, sometimes i see (depending on how cold it is where you are.)  when spark plugs wear out. or the type of plugs that are installed, it will cause a no start condition in cold weather, if you do have fuel and spark when cranking over then this is a good possibilty, so change the plugs and let me know what happens.
good luck
