If it were me, I'd switch out to synthetic oil. The difference in cranking speed between dino and synthetic at those temperatures is substantial.

When I screwed up the wire going to #1 GP the light didn't function.
I spliced the line and now the GP light comes on.
I have checked three GP's now and they all glow cherry red when I give them twelve volts.
I checked 1, 4 and 5. Four and five have those "hand tighten nuts" on them. They look like a knurled wheel. They seemed very loose when I started taking them off. I don't know if this was causing a bad contact or not but I tightened them down as much as I could with some pliers.
All that I have left to test are 2 and 3. Three also has the knurled wheel thingamajig and 2 has a nut that is as stubborn as 1.
Either they are too tight or they are locking nuts because they won't come loose unless they bring the post out with them.
I am thinking that my oil situation needs to be sorted out and my injectors need to be replaced.
Unless the two GP's I didn't check are bad, my only problem could be the oil and injectors.
