Visiting some relatives in Chicago and since yesterday, I've been having issues with starting the car when the temperature is extremely low (anything from below 0 to 20). I'll get it to crank, and it'll instantly die. Try again and it'll die. It'll then kick into safety mode and not let me start it anymore for a few minutes. This morning I got it to crank after pushing it into the garage with a little heater next to it, but it idled a little rough and died out after driving a mile or two. Got it start back up and let it idle to normal temp and had no problems afterwards. Now I tried to go out tonight and am having the same problem again, but this time I can't get it to stay running.

Not sure what the issue is at this point, going to assume one of the sensors (maybe coolant temp sensor or fuel pressure sensor?) though since it's never done this before except when the temperature got this low. Both battery and alternator tested out fine, checked at 3 different places. Coolant and brake fluid were all recently changed as well. Would be nice to fix it so I could drive home and leave this cold behind. My 350 has 120k miles now.

Pull the battery and reconnect it in the morning. I've never had this situation before tho. I'm not really sure why your issue would have to do with a cold environment. It may be a sensor failure. Good Luck.

Eh, that got me nowhere. Probably going to have it towed to the family's garage and let it sit in the heat for a bit and see if it starts then. Little frustrated with it at this point, even if it does start, I'll still need to find out why it's doing that if I plan on going into any more cold weather in the future.

Still no luck, car just start then dies. Goes into safe mode and won't let me start it again for a while. Really only thing I can immediately think of would be the fuel pressure sensor is going bad the the cold aggravated it.... Any ideas?

Have you put any gas line antifreeze into it. Like a fuel cleaner or HEET or something like that? It could be that you have some water in your fuel and it's freezing up.

Yeah, I put some in the other night thinking the same thing.

Fuel pressure sensor is bad.
