Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

A fuel pump or a coolant temp sensor will also cause this. Some testing and diagnostics would be in order at this point.

Please understand that I don't know your skill level or tools
you have to assist us. Also understand that I can't see, smell,
hear, or touch the vehicle either, so your patience is
appreciated. JA is a great Q/A site, but it does not replace a
repair shop. So please don’t shoot the messenger if I have to
deliver bad news:)
If you are satisfied with my answer, I would greatly
appreciate a 5 star rating now before you leave the site and I
will still assist you after you have rated me too if another
question pops up. I don’t get credit for helping you until
you rate me

Thanks, Ron

Great, test the pump then. Check for leaking injectors too.

Thanks again and please remember to rate me 5 stars now
and keep this link in case you need me again later on.
I don’t get credit for assisting you until you rate me

My goal is to assist you in the repair of your vehicle by
supplying you with well educated information. I may not
always have the exact fix you wanted to hear, but my job is
to get you on the right track, which I always do. I can’t hear,
see, smell or touch your vehicle from where I’m at, so your
understanding of that is greatly appreciated. There are no
magical answers, but I do my best to guide you in the right
direction.

fuel pressure drops overnight
BMW Mechanic: rpmdiag, Tech and Instructor replied 4 months ago

That's what I thought, then it takes a while of cranking for the fuel rail to refill. Most likely one or more leaking injectors.

Thanks again and please remember to rate me 5 stars now and keep our link just in case you need more help.
