What may be the cause of no start after replacing the coil ignigtion mod dist rotor crank sensor ran for three days and now dead again?

I'm always suspicious when a vehicle fails after a major repair. It's often one of the recently replaced components, but which one? See if you can find an OBD code scanner for your vehicle and try to read the computer code. Most electronic faults will show up, even if the engine won't run. You can borrow, rent or buy a code scanner from most auto parts retailers, and if they aren't busy, many will help you figure it out. You may need to tow the vehicle if you want them to help you.
