Did you check the coolant level in radiator. If the engine is difficult to start and struggles after starting and problem is not mechanically related, the highest possibility would be fuel pressure.

Before starting the engine, turn ignition switch ON for 2 seconds, OFF and back on again for 2 seconds and OFF. Repeat 2 or 3 tinmes and try starting. If starting is easier, check the fuel pressure. Either the fuel pump is weak or there is a leak in the line which normally occurs in the fuel tank, the hose between the pump and housing.

The videos you have seen regarding fuel pressure testing should be correct. Check out the following link.

No problem with cold start and only struggles when at operating temperature can be due to too low idling speed, valves clearances too tight, weak ignition coil and faulty ECT.
