Hello, my car hasnt been driven in 2-3 weeks and its getting colder and I tried to start it today, and it wouldn't fire up. So I tried swapping spark plugs
and still the same. Ignition is a Davis Unified Ignition system. It's around 35 degrees (fahrenheit) here.
The car is sold and it has to start:confused:

Did you check for spark from any of the plug wires? I assume you know it's getting fuel.
