Fixing Car That Cranks But Doesn Start Up

Hi there I am a mechanical technician engineer I fix the things normal mechanic cant! I fix mechanical and electric problem no matter what it is the problem with it!!!I I am very good and bless in my work I am 5gen mechanical engineering technician never have a problem I can not fix Its the ignition switch also have to check out the grounds for the whole car do a voltage drop test to find out the problem

The BMW 328i
Firstly clean the air filter as it seems that the engine is choking.
This should do it... if not...
Check the fuel filter and clean it ..you could use a good additive in your fuel to do he same.
The last resort will be to check the fuel pump as the right amount of fuel is not being delivered to the block.

Sounds like your fuel pump has stopped working get it checked out.

Come on give us more information. Think if you were trying to fix your own problem and you had to explain the problem to someone else with exactly no knowledge of what's going on.

1st off....a key with bad electronics and reader will open the door and that's it.

So that being said does the key turn the engine? If so the key, the program and ecu are ok. Say the engine cranks but doesn't start. Fuel pump. unscrew the access plug on the fuel rail and see if any fuel squirts out. NO......don't ever do this when it's hot..........not that yours is because it doesn't run but I had to say that. The millisecond you turn your key over to get it to try to start...the fuel pump comes on and pressurizes the entire fuel system.

Got fuel pressure, the engine turns but still no start= ignition spark plug engine computer problems.

then it is the actual buttons for the windows on the rear doors
