It was cold last night, somewheres around -16C. I didnt plug it in, as the block heater dowsnt work. So I get in this morning and try to turn it over: it does, but too frozen to catch. So I hook up my girlfriends Intrepid to the Bronco with the cables. It comes close to starting, but still no dice.
Question is, does her car simply not have enough juice to jump the truck, and should I ask my old man to jump me with his 3/4 ton?
Is your truck actually cranking or is there not enough juice to get the starter to turn the motor? If not, then its most likely just the combination of the cold and the weakened battery in your truck. If the sstarter is actually truing the motor then you have lost one of the three ingredients for ignition. Air - highly unlikely, spark - easily checked by removing the coil wire and watching for the arc to jump, fuel, the most likely culprit especially given the extreme low temps. pressure regulator can stick and ice can form in the lines if there is any moisture in the fuel.
The starter is working, the truck is cranking over. Quickly at first, then slower. I threw a can of gas line antifreeze in it yesterday because the tank was nearing empty. Didnt check for spark though.

BTW, although I havent checked, I do not think that there is any parasitic battery drain, or problems with the alternator. The truck starts right up all the time, and on cold days. This one was just colder than usual.
