Z3 BMW cranks but not start

SOURCE: bmw 318 i cranks but wont turn over

Ok , when u turn the key the engine cranks (turn over is the same as cranks), but it won't start. U have to determine if there is spark at the spark plugs, if there is then u have to determine if gas is reaching the spark plugs. This must be fixed 1st before the running hot issue, and I don't believe the catalytic converter has anything to do w/ your problems you have described.
So 1st u must get the car running again. As far as overheating, why did the shop think it was the head gasket? So u have several problems, but unfortunately, not enough information to work with yet. Let me know when u determine if the no start issue is due to no spark, or no gas. Good Luck!

Could be a fuse or a relay or fuel system gunk in cold weather!
Try a can of Starter fluid sprayed in the air filter!
If it starts and stays running it could be just gunk or junk in the gas tank!
Do you ride til the tanks empty?
If so fill the tank with high test or just get the starter fluid and some expensive ($10) fuel system cleaner to add to your tank and try it again!
If this doesn't work look for a bad relay or fuse at your local auto parts store. Advance Auto Parts is my favorite....they will probably tell you where the relay is located and may let you return it if it doesn't work. They're very helpful!

AS SILLY AS IT SOUNDS ITS YOUR MAX AIR FLOW METER,OR COULD EVEN BE A REALLY DIRTY AIR FILTER, SERIUOSLY BMW HAD MY CAR IN COULDNT FIX IT, MISSED THE FACT THE AIR FILTER WAS FILTHY AND NOT LETTING ENOUGH AIR THROUGH, ICHANGED IT AND IT STARTED FIRST TURN

SOURCE: Will the wheels from a BMW Z3 M fit a 1999 BMW Z3 2.8 ltr roadster?

yes they will you just may need to use a wheel spacer

SOURCE: BMW Z3 rough idle on start codes read P1189 , P0173

all the codes you have are all related to the fuel trim, this problem needs to be looked at with a european capable scanner for futher tests sorry.
