Your fuel injection pressure is probably leaking down causing gasoline to leak into the cylinders and resulting in a hard hot starting condition due to "flooding" of the engine. Try holding the accelerator pedal all the way to the floor of the car like your trying to go maximum speed down the highway and crank the engine for 10 seconds or less at a time. That tells your computer to enter the "clear flood" mode and stop injecting gas into the engine. Ask your repair shop to measure the fuel pressure and see if the pressure is bleeding off too rapidly.

Car wont start when warm


It always helps to tell us what you are working on. Could be bad coolant temp sensor; bad coil or module (these heat up after you turn hot engine off); improper fuel pressure (test with gauge); leaky injector(s).

My BMW 520i starts up when cold but when it's warmed up and I turn engine off it won't start it's a 1997 straight six tiptronic whats causing this?


If the engine cranks but fails to fire, the car may be flooding due to a failed temperature sensor. There are several, but the most likely problem would be the water temperature sensor.
If the engine fails to crank when hot, the starter motor is failing and will need to be replaced.

Car turns over well fires but wont run


you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

CAR SOMETIMES WONT START


you are having a fuel delivery problem...and it could be caused by numerous things...such as a bad fuel pump, a bad cold sensor or warm up injector.  You haven't attempted to  solve any of these suspected faults...so take it to a mechanic for repair

BMW 318i wont start engine


I would have the battery tested. When they get cold they get weak. Next I would look at the wires on the starter to see if their loose.

check and see if you get water/coolant circulates when you have the cap off (only check from cold start) the original water pump came with a plastic impeller and tends to strip on the shaft also check your thermostat before replacing water pump.
