Re: 91 4.3 hard starting problem
How cold are we talking starting here? Depending on just how cold, 91's have a block heater, which you may want to give a try. Check out the manual if you still got it, (If not I'd be happy to copy the page for you and send it to ya), and it will tell you where and how to find and use the block heater. I know not all of them come with one, my friends didnt, but he got it installed for when we went to Aspen, it worked pretty well. As I recall it was fairly inexpensive, and may be worth giving a try.
