A loose positive battery cable connection will kill a battery in short order. Tighten all the connections including the starter (usually hard to get at - and most likely the culprit).

It is a good idea to check the cables periodically for corrosion, this can also kill your battery. Once you have made sure the connections are free of corrosion and have a tight fit you can recharge your battery or replace it with a new one if the battery is damaged from being undercharged.

Another thing that will kill your battery is the charging system voltage regulator - if it dies your battery will run out of power just running the engine. Modern cars have this part in the alternator and you may or may not be able to replace the regulator. Take your alternator to a parts store or a shop and have it tested. If it is bad and you put a new battery in the car, the new battery will die.

Try the earth and main active leads to the starter motor. Or If you are shorting the solenoid and it starts, there will be a problem with either the active wire from the ignition switch or a poor earth. Check what voltage you are getting to the solenoid from the ignition switch when someone turns the switch on.

I can't give you a cure for your problem online as testing MUST be done. Computer scanning and individual Component tests are the only way to verify a failure. If a shop is doing the work, I certainly hope they aren't charging you for iteems replaced that did nothing towards making an adequate repair.
Off hand, I'd be looking for a bad connection such as inside the ignition switch or since you mentioned a timing sensor (there is no such thing) either you replaced the crank position sensor or the cam sensor. Whichever was replaced, check the other one.
Wiring failures most often happen at the connector pins or behind the connector plug where moisture gets in and corrodes the internal connection. All of that needs to be tested for continuity and resistance.
