Herein, what causes a car to lose all electrical power?
If the problem is a bad alternator, your car will slowly lose power. You'll be driving down the road, your lights will dim, and you'll lose power and die. Other problems can also cause a car to not start. It could be a bad starter, corroded cables, or a broken connection somewhere between the battery and starter.
Also, when your car won't start but all the lights come on? Broken or Damaged Ignition If your headlights can turn on, but your car won't crank, that means that your battery is charged, but either the starter or ignition is the problem.

Keeping this in view, can a blown fuse cause your car not to start?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won't start.
How do you know if your car has an electrical problem?
Check the ground connection with your ohmmeter. If the ground connection is good, the fault is inside the component. If there is no voltage in the "hot" wire to the component, then the problem is in the wiring. Trace back through the fuse panel (or relay or circuit breaker) until you find voltage.
