I have roadside assistance on my insurance so I'll have it towed in, they'll put in a new battery and check everything. I don't have an easy way to go get a battery, where I live is far away from everything, and my other car is in the shop too.
That is what I have needed for years. I have found myself changing a fuel pump on the side of the road before...... in blowing snow, because I refused to leave the car.
A broken z bar in 2016, a weld let go , so lost the pedal and had to keep shutting it off and on to control the engine all the way home.
Tire blowouts, snapped throttle linkage, going home on 4 cylinders. You name it
Be happy you have an old car to keep you busy, life can get boring with nothing to do
