96 blazer wont start in the cold

[loaderman]

i have a 96 blazer that wont start when its cold, i can pour gas in it and it will start and run fine till it seats over night then the same thing but if its above 40 out it will start on it own i,ve replaced the fuel pump and the spider injecters plus fuel pressure regulator theres not much more that i can replace it seems to me it has to be a sensor of some kind

man o man good luck!
mine was doing the same thing exactly, it hasnt done it the last couple weeks.i found a couple of vac lines loose. one to the 4 wheel drive actuator under the batter and one to the vac ball mounted to the hood. fixed them and it hasnt done it since. dont know how the would cause what it was doing or even if it was for sure.
i also replaced the fuel pump and the crank sensor.. witrh no luck
