What would cause a 1994 Volvo 940 not to start?

A 1994 Volvo 940 might not start due to several issues, including a dead battery, faulty ignition components such as the ignition coil or spark plugs, or problems with the fuel delivery system, like a clogged fuel filter or failing fuel pump. Additionally, issues with the starter motor or electrical connections could prevent the engine from cranking. Checking these components systematically can help identify the root cause of the problem.
