You need a professional mechanic with a scanner. Never drive a car with a flashing check engine light except to get it off the road. Flash = serious issue.

Have the EGR valve checked. This unit is the exhaust gas recirculation valve and when faulty it WILL cause loss of power.

Sounds like the transmission interlock switch for the starting circuit is malfunctioning. It keeps the car from starting in gearshift position but park.
The interlock switch can be temporarily jumped out of the circuit to test if this alleviates the starting issue.
If it does, get repaired immediately since this is a safety feature.

Talk to the person you bought it from. Ask if it happened to them. YOu don't describe what is not working. Is the starter turning the engine over? Is there spark? Is there gas? Etc

Most likely your key has failed. You should find and try your spare key if you still have it. If not, then you will require someone with a tool to scan immobilizer codes and verify if there is a fault in the immo system or if it simply is saying INVALID KEY. If its faulted, it will require repairs. If its invalid key, you can use your backup key, or have a new key programmed by a mechanic or locksmith with key programming tools

Black Smoke is too much fuel, Blue Smoke is Oil and White Smoke is Coolant. Sounds like the Catalytic Converter is burning itself out because of too much fuel.

A lot of the newer Volvo and Ford cars have Electronic Accelerator / throttle pedals fitted which play up when worn.

Many complete Accelerator pedals are compatible with the Ford Focus cars in the UK.
