Mazda cx 7 hard to start when warm
Hi All
I have a 2009 CX 7 and when it’s warm (after driving for at least 20 minutes and turn off for 5 mins), hard to start. Sometime takes 4-5 cranks to start. It starts fine when it’s cold.
Went to mechanic, he changed the air flow sensor and crank sensor however the problem is still there. Seems to me it doesn’t get fuel. I am thinking of either fuel injectors or fuel pump or engine coolant temperature sensor.
Any suggestion would be helpful.
Thanks

Get someone to check fuel pressure. If it drops off/drains off with the key off, then you have an issue.
Has it been scanned for fault codes?

Sure I will ask my mechanic to check the fuel pressure.
It has been scanned for fault codes and that’s why my mechanic changed airflow sensor and crank sensor. Now codes are fine.
I will keep you posted.
