Engine Failsafe Prog and Frozen Pulley?

[weiln12]

All,

When it was VERY cold the other day (-21*F) it started and gave me a "Engine Failsafe Prog". Also, since it's been cold it makes a "vroom" sound, like the sound on a toy when you pull the cord and get it spinning. It made that sound which then stopped abruptly. I tried looking into the engine compartment and I think one of the pulley's froze on the tensioner. Would that generate the "Engine Failsafe Prog", or would it be something else? I stopped and re-started and it didn't make any noise and no failsafe prog.

Long story short, I'm debating parking it for now until I can tear the whole front end off and replace everything. I don't have a garage to park it in overnight and I'm afraid these very cold temps are just going to kill it...

I'm hoping to have a garage within a month though.
