Dear Sind,
It is miserable trying to work on a car in the cold. So...let's start with trying to get your car started without the block heater.
Several old farmer tricks in priority:
a) Starter fluid-
http://en.wikipedia.org/wiki/Starting_fluidThis has a boiling point of -44F, and is used for starting in Fort Greeley, Alaska.
B) Battery-Disconnect the battery, bring it indoors near a room temperature heat source to warm to 70F, reinstall and reconnect.
c) Intake manifold-If you can get a propane torch or old fashioned blow torch to fire and hold a flame, you can use this on the intake manifold ONLY, to warm the manifold so that the air entering the engine is heated. don't burn your wiring or control cables...the manifold can take a lot of heat but the other parts nearby cannot. Don't heat your fuel injectors or fuel gallery.
d) Oil-last resort...drain your motor oil, put it in a large stock pot that is not the Mrs. favorite, heat on the stove to 120 degrees, reinstall in the engine.
Now you can at least drive the car to a warmer spot to work on it, maybe even a heated garage or dealership.
