so anyway I try to start my truck earlier today, was around -25*C and i had her plugged in. Turn the key, would fire right up, and then the rpm wouldnt even hold for a second, and it would die. Did this maybe 5 or 6 times trying different things, with nothing. Then I gave it one more shot and it held out [&:]

It did this same thing about a year ago also.....Also on cold startups without being plugged in right after it cranks i hear a loud, quick(less than 1/2 a second) grinding or "err!" only seems to do it when its cold.

Are these problems related to my starter, or "ignition control module/box" thingy?

battery and alt. are less than a year old.

 

ok the grinding kind of sounds like a bad starter clutch...maybe? not too familiar with chev starters--seems i only ever help replace my buddies' rice burner pull cords lol

try using a gas line antifreeze every few tanks--you might just be getting a bit of icing in your fuel lines....

another possibility would be fuel sending unit........but id try a .99 cent bottle first. lol

 

you my need to clean your idle control vale with some cleaner i had to do in on my kid blazer ez to do just remove the two screw holding in and clean where the pluger go in pluse clean the plunger to then spray a little wd40 in the hole a reinstill.
