Well a week before the car was to be dropped off to be painted it’s giving me issues by not starting. At first the problem started by taking a long time to start. Then one day I went out to my car and tried to start and no go. I scanned the car for codes and only get issues for the secondary air injection pump. The starter, batteries , fuel pump , fuel filter , spark plugs, crankshaft position sensor, coils are under 2 years old and less than 10k miles old.. The only things I did check is the fuel pump fuse and relay. I think I hear the relay click on for the fuel pump but not sure. What I don’t hear is the humming noise for fuel pump when I turn the key onto accessories. Any one can think of something I am missing?

CPS ? cheap and simple
always best to differentiate no crank, from not firing, and even on to won't run

Botus,
normally you would get a code for the cps? I know this isn’t a great idea but I bought a bunch of parts that I am going to try. These are the following parts : CPS, fuel pump, and fuel pump relay. Normally I wouldn’t do this but I am going to try these parts one by one.

on the fuel filters the car "doesn't have" I found out something I never knew....
currently driving a toyota that seems to have low first start fuel pressure issue - everyone fits a pump and yet it makes no difference, so you find better websites and youtube videos and they all say the fuel pressure regulator is rubbish replace and its great....
to get at either of these parts, its all part of a white plastic tank drop in unit with the pump, pressure regulator and even the float level sensor attached with a nasty coarse filter sock at the bottom...
so I go to an indy toyota bod for info on what part I likely need - he says what mileage - when I say about 150k miles, he says change the filter first, so I say what its only got the silly sock - and he looks at me like I'm a moron and he repeats change the filter and that's more or less all he wants to say.... so I go to the dealership and say do you have a filter for toyota corolla xxx, expecting him to say they don't have one - and he goes what one of these and hands me this massive chunk of $55 white plastic that's the bit that sits in the top of the tank and all the bits clip on too....
when its new and the plastic hasn't bathed in grotty fuel for 16 years you can sits inside its a really a silly complicated specialist filter - and magically a day later on a bike forum I have followed for 7 years, turns out just about no BMW bike owner knows the same silly chunk of plastic is a fuel filter on these too !!!!
which now makes me think "the fuel filter we don't have on the 221" is likely the same idea - and the bit many in last year say they changed - means do we really have the same mess up too ???
if so, rather than a sensible easily replaced cheap service item, they secretly hide a mess up that costs too much and we are not supposed to ever know its there as part of the design to fail ideology....

Botus,
the fuel pump and fuel filter were replaced June of 2022.

yes the great idea of a hard to reach filter is we'll never know if you got a batch of rubbish fuel that filled it up and blocked things
error codes - don't remember - when its playing up they don't work - but when just being random you don't always get a engine light on the cluster

Botus,
I found the issue. The starter battery was at 47%.. the battery is just barely 2 years old and has a 3 year warranty. I will be bringing back to the place that I bought it. I was able to start it by jumpstarting the starter battery.

well… I was wrong. It’s the not starter battery at all. I confirmed exactly what it is and I am bit annoyed lol.. it’s the rear relay plate for the rear sam. When I press the relay plate down it makes proper connection I am guessing to the contacts inside of it and the car starts right up. Needless to say I noticed that the part # on my relay plate is A2215450801 and I also noticed that the relay plate # on a 2010-2014 w221 base is A2215450801. Apparently this part fits 07-10 years. I want to buy this part brand new as this is the second relay plate that caused this issue.
