Hello,
I'm in need of help diagnosing the problem with my '06 e90 330i warm/hot start. Awesome helpers in this forum has made this forum so awesome. And thank you all for your contributions.
As the title says I'm having issues with hot/warm start. Cold start fires right up. But when it is hot/warm after the engine reaches normal temperature and park it for more than an hour or longer it takes 2-3 cranks to start the engine. So, far I have replaced coolant temp sensor, engine oil/coolant temp sensor, fuel rail(found pressure leaking from shrader valve), reman. injectors and the problem is still there.
Any suggestions or solutions would be highly appreciated.
Thank you all

Are you sure your battery is good?
Are you on the original battery?

No, it's an autocraft battery 49H8 and the date on it is 05/13 and there's no history of registration when checked with DIS. And that's how I bought it couple of months ago. Should I consider Autocraft platinum AGM battery with coding and registration?
Since it fires right up during cold start, I didn't suspect the battery.
Thank you for the response.

Have you done a fuel system pressure check? In my experience most issues starting a motor when hot are fuel related. For example Fuel Pump pressure too low

I haven't tested it yet but I'll test it soon. Btw, I also have continuity on both wires for engine coolant/oil temperature sensor. Is it normal or I have short somewhere else and causing this issue?
Thanks
