Hey guys/girls
My wife has a 2003 mazda 6 2.3l gy wagon.
The issues im having is when she starts in the morning its fine, but when its been for a drive and engine is hot(warm) she will struggle to start but will eventually start after its turned over a few times.
Ive changed the in tank fuel pump and the gauze filter as i know these cause that issue,but still the issue remains, has anyone had an issue where the fuel pressure regulator causes this issue? Ive checked and cleaned mass airflow.
Only thoughts i have left is crank sensor issue? Fuel pressure regulator or temp sensor?

Any help grately appreciated :)
