I am now standing in a mixture of cooling fluid, gasoline, and cola.

The difference between screwing around and science is writing it down.

In theory, cars are fairly simple. If they don't start, it's either the fuel system or the electrical system. Teach yourself about the path of each in your engine and tracing it is fairly straightforward. But at the beginning, mastering each new system seems like an unreachable shore. The car is effectively a black box.
