Car turns on no problem but at times when I drive and park it and start it again it take 2-3 tries before it actually starts, it feels like it wants to start but cuts off. Any ideas?
Do you
have the same problem?

Good afternoon,

When it does not start, how long does it take to start?

This could be fuel delivery or a possible crank sensor issue.

Can you check the fuel pressure?

Are there any codes set?

I would verify the fuel pressure.

You need to rent a gauge at a parts store and check it with key on, engine off and also when it is running.
