What to check next
Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.
Have the fault tested while the engine actually refuses to start. Record cranking RPM and fault data, then check ignition output, injector command and fuel pressure using the vehicle's procedure and suitable equipment. Hearing a pump is not a substitute for measuring fuel delivery, and a missing RPM reading needs circuit diagnosis before replacing a crankshaft sensor. Note whether restarting becomes possible after cooling and how long that takes. Avoid repeated prolonged cranking. Separating a missing speed signal, ignition problem and fuel-delivery problem during the failure gives this intermittent condition a focused diagnostic path.
Guidance references and applicability
HELLA: Crankshaft-sensor diagnosis https://www.hella.com/techworld/en/technical/sensors-and-actuators/crankshaft-sensor/ Explains the engine-speed signal and checking the sensor circuit. A missing scanner RPM reading alone does not prove that the sensor itself is faulty. HELLA: Injection-valve diagnosis https://www.hella.com/techworld/en/technical/sensors-and-actuators/injection-nozzle/ General injector and circuit diagnostic background. This is not a vehicle-specific removal procedure, seal specification or proof that an injector failed.
Do you mean it is not cranking over (starter) or do you mean the engine cranks over but not run? here are two videos to get us started on fixing the problem.

The engine cranks over but dont run

Chances are it is the fuel pump or crankshaft angle sensor. These cars had both problems, we need to see which system is failing, when the engine will not start, turn the key in the ON position without cranking the engine over, do you hear the fuel pump run for 5 seconds in the tank? Also, the video shows how to check for spark, this will tell us if the crankshaft sensor is working, or you can connect a scanner to it to see if it reads engine RPM while cranking. Let me know please.

Discussion summary
Not starting back up after driving it a mile?
The owner reported failure to restart after driving a short distance and clarified that the engine cranked but did not run. A contributor suggested checking fuel delivery and crankshaft-speed information. No test results were supplied.
Reported outcome: No faulty component or successful repair was identified.
The discussion does not establish that either the fuel pump or crankshaft sensor failed. Pump run time and pressure specifications were not verified.
