The car was sitting for 6 days, the last 3 were at -37C. I didn't have it plugged in, I have an 800 CCA battery. In the evening I started the car with a remote starter from the house with no problem. It ran for 8 minutes and I shut it off. If it didn't start I would have plugged it in.
The next morning I started it with the remote starter and it ran for about 5 minutes before I got in. The oil light was on and then I remembered that the motor was running a little rough. I stopped the car and checked the oil. It was at the top of the cross hatch area, meaning just right. I got back in and it started with no problem. I drove it with the oil light on and the Check Engine Light was not on. The car stalled about 6 blocks later. It now doesn't want to start, even when boosted. It didn't seem like it would take a charge. The lights are all bright until I try to start it.

Replace the fuel pump/oil pressure sending unit also see below how your fuel system wired in with the oil sending unit. When oil pressure is built up it will close the switch to power the pump-also might want to check the oil pressure if the oil pump is weak it will not close the switch to power the fuel pump constantly that's probably why it died 6 blocks later when the oil light came back up no oil pressure.
