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?

It’ll start after about 2 or 3 cranks like on the first ones it wants to start but like fails. it feels like it wants to start but doesn’t, but it’s not always only sometimes it happens.

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.
