Which sensor are you referring to? Also, is there spark and fuel to the engine?

Crankshaft position sensor, there's spark and fuel to engine, if I jumped it, works fine

Okay, if you have spark and fuel to the engine, it should run. Are you sure the fuel pressure is within the manufacturer's specs and the spark is a good hot blue snapping spark? Also, make sure the fuel injectors are getting power.

Fuel pressure don't know, fuel injectors are power yes.

If there is no power to the crank sensor, check the wiring between it and the PCM. Check the plug on PCM for corrosion or damage.
