98 740i Crank but No Start

I am new to the forum and this is my first BMW vehicle to own... Had it for about 2 weeks now and all of a sudden, it would crank and not start after just coming back from the store 2 minutes prior.
Someone thought battery so we tried to jump it, No Luck, someone said the fuel pump was not running so tested the fuel pump to a battery... the fuel pump is fine but does not turn on when connected in vehicle. Someone suggested Fuel Pump Relay so that was replaced... Both fuses 17, 57 was checked in vehicle... Cranks but no start still.
Sprayed Starter Fluid into Air Intake, cranks, starts, chokes, then stops... Someone suggested the Crankshaft Position Sensor and Cam Sensor... other than those two sensors, anyone else have any other suggestions?
We are pulling our hairs out since this is our only vehicle....
