E300TD won't start

[blueline]

99 e300, 168k miles. Wife backed it out of garage Thanksgiving. Went to put it in later that night (temp was around 18) and it wouldn't start. Pushed it back in heated garage and still won't start. Just cranks but acts like it's not getting fuel. No other symptoms, signs, check engine lights etc. Been running great. Glow plugs were changed 1.5 years ago. Never had a problem before.

Any ideas before I call for a tow and bring it to the shop? I have limited mech. ability and time to fix myself.

thanks! Brad
