If it's a gasoline engine, please check for sparks at the spark plug end. If it's a diesel, check pre-heating system. Starter fluid in the throttle body must be ignited by the spark plugs. For diesel, pre-heating is necessary to ignite the fuel.
Stalling and running rich. I have seen this before on a Camero. The fuel pump was weak. Not making enough pressure. This caused the fuel injector to DRIP gas instead of SPRAY gas. This caused the fuel to flow into the cylinder in a liquid form, and it did not burn well. We put in a new fuel pump and the car came to life. Good luck.
Have you changed the fuel filter? Did it die while driving, or just wouldn't start? Don't use starting fluid on a gas engine! It will cause a lot more problems than it solves. Ether, starting fluid is made for diesel engines... not gas, not ever. If it won't start, it isn't lacking ether. It's lacking gas, air or spark.
Try changing your filter first if that does not work it could be your pump. It is possible for the pump to still pump fuel up through your filter but if it is not putting out sufficient pressure then your car wont start. Most fuel injection systems require around 35psi to fire the injectors.
did you use carb cleaner or starter fluid. if you try starter fluid and it starts for a second and then dies you might have a fuel pressure issue. if not check for spark.
No spark issue can be from a number of causes. Most likely the crankshaft position sensor. It is sensitive to minor damages. check position of the teeth. If bent carefully straighten. Also can be the ECM (main computer) On cars with no fuel pressure check oil sending unit because a faulty one that tells no oil pressure will make computer cut out fuel pump operation.
