I live in washington state, and I work early in the morning, and lately its been around 30 in the mornings. My problem is that this car doesnt like to start in the cold. I was wondering if it would be wise to rewire the glowplugs so they run on an independent battery so they can still glow when the starter is going. Ive noticed that the car will almost start for like 2 or 3 seconds, I figure because the plugs are nice and warm, and then it kinda flatlines.

Has this been done before? Did it work?
