I've noticed over the last couple months that my suburban won't start if the temp drops below 35 degrees. i've recently put in a new battery, a new starter, new fuel filter along with a fuel treatment. after the treatment it seemed to start & run just fine until it this weekend when it got really cold and we got a lot of snow. The week prior, it was in the mid 60's and it started right up but the week before that it was cold and didn't start. Any ideas?

Re: 1996 chevy suburban won't start in cold weather
Could be excessive water in the fuel system. This will freeze in low temps. Run several tanks of gas using fuel antifreeze. Basically alcohol which absorbs the water and carries it to the cylinder to be burned. Use the mixture as instructed. adding too much in not better and will adversely effect hoses and seals.

Coming from someone who has worked for Chevy,Ford,and Chrysler dealerships we had to gauge the tires by what the sticker said on the door jam at the driver side..I disagree with it...It is always best to gauge tires with the outside temp because cold weather and hot weather make a huge difference...NASCAR racing can drop a tire pressure on one tire and raise it on another for better traction on the constant left hand turns...Just a 1/2 of a pound can make a huge difference..Tires tend to swell in hot weather and on long trips..another reason it normally says to gauge a tire while it is cold which means been sitting still overnight..It doesn't mean cold weather...However tires won't swell in cold weather...I like running 40 psi in tires if it says 32 or 35....this will give you a good flat even tire wear...I have always added 5 pound to whatever it told me to gauge it at...If a tire wears out on both edges it indicates low air ..,also tire alignment can wear one side of the tire....If it wears in the center it means too much air...It is hard to keep them perfect because of rotations..,weather ,and certain terrain but it can be done by checking them every month....Some tires have different pressures written on them that is different than the door sticker...To answer your question ...Add 5 pounds to the door sticker...,your tires will last longer..They won't last as long with door sticker pressures which will give dealers more tire business...Another thing dealers do is put nitrous in tires instead of air which is supposed to keep air from swelling and changing in the summer and winter...This is good..It isn't Nitro that explodes.....Always tell them to gauge them with your choice of tire pressure....
without actually hooking up a scan tool and looking at the pid data i would say you have either a coolant temp sensor issue or intake air temp sensor issue.i have seen alot more coolant temp sensors bad than the intake air temp sensors tho.
it could be a tune up issue such as plug wires plugs . but my guess is its a computer engine temp sensor if it reads 5 degrees out of range it cuold give you a hard start or a no start problems the best way to look at this problem is with a scan tool when it is cold to see if the temp matches outside ambeint air temp 1 or 2 degrees ok b ut not 4 to five there is a nother way to check it buy useing dvom at a temp to omhs chart.
I have the same problem, Noticing that my 2006 Saturn Vue, 5-speed becomes extremely hard to shift
gears when the weather is cold. (Temps range from 20-43). Has been colder in the last month. What could this be?
also side note: Our windshield wiper spray doesn't work on front window but work on back. They both started about the same time when the temps dropped to single digits. Dont know if that had any causes.
