Could it be the ICP sensor?

[racejosh]

i have a 1996 F350 cab&chassis with 365k miles and when i leave it out in the cold she wont start in the morning so ive replaces all the glow plugs and replaced the whole block heater assembly thinkin that it was burnt out of something like that and she still doesent start. the only way she will start is if i put a propane heater under it and let it warm up for a couple hours or if i put it in the garage over night. could it be the icp sensor or another sensor or just too cold and aslo i am not getting any engine code. and when it is outside and i crank her over with the heater under it it will kick like it trying to start and when it does start it will run very ruff and sometime stall a few times, any ideas?

Have you checked compression with all those miles?

Negative. i dont think i have a bum cylinder maybe a lil blowby but once she starts up she has plenty of power and use her daily to tow cars. its just starting in the cold so thats why im wondering if it could be a sensor.
